Hi,i’m now using jumpstart ,instead of autodial ,as my homepage
and i think there is something we have to learn from other addons.
for example,speeddial ,it supports HIGH QUALITY scaling ,so thumbnails are
very clear.
it also supports manually setting how many pages you want to display in the
new tab,so either 3*3 OR 4*4 will be OK.
capture delay is also a good design,you can set a timing to delay for pages
that load slowly(Google Reader,e.g),otherwise the capture might be incomplete.

just some advice.JumpStart should be the best addon that i,ve ever used.
