Are they currently just lining up in order of installation?

It'd be great if you could drop them elsewhere on the toolbar too, like on the left 
side.  (I've always wanted a Stop button next to Reload, myself.)

On a related note, Issue 24498.

yea, you should be able to drag move them.

This feature is needed soon.

 Issue 21236  is a dup.

 Issue 21236  has been merged into this issue.

can someone triage this and give an owner? this is required for browser action!!!

Sorry, I don't think this is going to make it for the initial release.  We understand 
it's an important issue, but our UI has been frozen for a little while now.

fine.. just wanted to be sure that you would start soon to work on this. Mstone 5 is 
ok! thank you and continue the great job guys ;)

Extensions: create a simple model for the browser action buttons toolstrip and use it on Linux.

TODO: persist the order of buttons
TODO: use the model on windows, mac
TODO: let the view change the order of buttons

My plan for persisting the order is just to write/read a simple text file to/from disk, one extension id per line. Similar to the bookmark model, except that is structured data (because they try to hold more information).

please this needs an owner for windows/mac! the number of extensions is growing fast.. 
is necessary a way to reordering them!

thanks ;)

in the meantime the best workaround is to disable all extensions, then re-enable them 
in the order you want them to appear on the shelf

this does not work for me! the order seems not to be releted to the order of enabling. 
oor better is not persistent between sessions! am i wrong?

@20
That new order will only work until you restart the browser.

Support reordering of Browser Actions within the container. Currently does not support dragging to/from the chevron menu.

Also fixed two bugs in the same code:
- the container would be 0 width if a value for it hasn't been saved (part of  bug 32101 ).
- the default icon was not used when a tab specific icon was not found ( bug 34317 ).

BUG=http://crbug.com/26990, http://crbug.com/32101, http://crbug.com/34317
TEST=In both LTR and RTL locale, try reordering the browser actions and make sure to test dragging to the ends with and without a chevron visible. Install Send to Gmail extension and make sure it has an icon while in the overflow menu.

Windows is done. Just Mac to go, I guess?

Is Andy an appropriate owner?

I know this sounds picky, but wouldn't it look cooler if the dragging worked like the 
NTP dragging?

Yes I'm the appropriate owner. Thanks, finnur. 

Is there a UI spec somewhere or should I just find a linux/win build to play with?

I'll find one for you tomorrow.

Will this be in next Windows dev

@GraemeErickson, are you suggesting that dragging the extensions work like the NTP 
dragging that also swaps the locations?

If that's the case, then NO WAY!  Dragging only one extension and inserting only that 
extension into the dropped location is perfect and the only way to go.

@krtulmay, no, I dislike the swap function as much as you do. What I'm talking about is 
how the thumbnail drags with your cursor as you move it. Currently in Chromium, there 
are just dividers between the browser actions as you move them around. I think it would 
look less IE-ish and more Chrome-ish if the browser actions moved around with your 
cursor.

> more Chrome-ish if the browser actions moved around with your cursor

Yes, that would be more Chrome-ish and sounds like a neat idea!  Sounds like it should 
go into its own bug report/feature request.

Working fine on latest Windows.

Can't wait!!!! Hopefully this will allow users to place extensions and all icons where 
ever we want on the toolbar, including of the far left.

thanks google

bmcfiv: Just so that there is no misunderstanding: This changelist does not allow you 
to move the browser action container anywhere, only reorder the icons within it.

There is another bug describing a feature request to move the browser action container. 
You might want to hunt that down and star it to keep track of updates.

too bad but thanks for the response.  i will do that.

For those interested in moving built-in functions, please vote for Issue 24498.

I like that the badge moves with the cursor now, but I still think it'd look cooler if 
they "slid" across the container, rather than dropped into a spot. I'm thinking of how 
thumbnails can slide around the NTP. It'd also be cool if, like the NTP, a badge would 
slide over if you moved another badge over it.

I like having the slider, but I think it would be better if it was invisible and the 
then the cursor changes when it hovers over the area; much like in firefox between the 
location bar and search bar. Does anyone know if there is an 'issue' regarding this, 
and if so what number is it?

o Dragging the resizer actually resizes the container.
o Known issues include:
  + no chevron.
  + no updating of other windows if the size of the container changes.
  + the cursor is a bit wonky in updating its state.
o Fixes a slew of janky UI bugs relating to having a lot of extensions installed.

Merge 41114 - [Mac] More progress towards resizing the Browser Actions container.
o Icons fade out as they are moved off screen by resizing the window.
o Dragging the resizer actually resizes the container.
o Known issues include:
  + no chevron.
  + no updating of other windows if the size of the container changes.
  + the cursor is a bit wonky in updating its state.
o Fixes a slew of janky UI bugs relating to having a lot of extensions installed.

[Mac] Enables drag N' drop for the buttons within the Browser Actions container. Also fixes an issue where the grippy was being shown when no Browser Actions were installed.
Known issue: You can drag the buttons outside of the container, even though they will recover by snapping back into place. This will be fixed in a further revision.

TEST=try dragging browser action buttons in order to reorder them.
