I've seen this brought up in the support forum, and I believe it may already be in progress, but I figured it'd be good to have an "official" feature request in the Project page;

I'd like to request a "Tablet" display mode, for large / high-res screens on tablets. Something with a vertical columns for the mail list, etc. It would be great to have this before the release of Honeycomb, since there are already a lot of android tablets on the market.

It's actually something I'm already working on.

http://fsck.com/~jesse/tmp/2011-01-12/667e9f21-5daf-44e8-8714-4106a90a178c/k9tab.png is my current WIP. Nowhere near ready for release.

Is that a screenshot from a device or from an emulator? Is that the nookcolor?

It's from an emulator.

This is what I've been waiting for. Many thanks for the excellent work.

Nice to hear that you are working on a tablet version. But your posted picture looks like you are don't using the new UI elements specially for Honeycomb. There are new UI features in the new SDK: http://developer.android.com/sdk/android-3.0-highlights.html#ui

You are correct.

Doing so would basically kill our ability to run on anything 2.3 or earlier. It's frustrating, but the options would be to either kill support for every android device already shipped or to fork the application.

wow, that's bad. I really love k9mail and I used it since I owned my android phone. But the new Android Gmail app on Honeycomb looks awesome :-( But I don't want to use gmail, because I have my own imap server, so k9mail with Honeycomb features would be more awesome ;-)

yep. we have some work to do to beat their new ui

the newest blogpost on "Android developers" is about the new Fragments API in Android 3.0. In the conclusion section on the bottom of the post they wrote that they want to provide a solution for all applications which should also run on older Android versions. This could be a solution if Google will publish this new library the talk about in the blogpost: http://android-developers.blogspot.com/2011/02/android-30-fragments-api.html

there is a new blogpost on "Android developers" and the Fragments API is now available for the older Anroid versions as a static library: http://android-developers.blogspot.com/2011/03/fragments-for-all.html

Just to say I've now got a Honeycomb tab (Asus Eee) and would be very interested in this, long-time K9 user, happy to beta test.

I, too, am a longtime k-9 user and have recently started using a tablet. Can't wait to see this. Happy to test as well.

Another Asus Transformer user here to betatest.

No progress on this issue?

Prodding to ask if there has been any progress - also an Asus Transformer user happy to betatest

the progress went here: https://play.google.com/store/apps/details?id=com.kaitenmail

so this feature will never be in K9 ?

it will, but only when we fully support the android ICS features like fragments and stuff. This is alot of work and perhaps we have to discontinue <4 devices - so not an option for now.

done in 4.4
