Apparently I can't resize dockers as well as I could before, the tools docker is now forced to a minimum width where it is so wide that the icons are set up in two rows (not cool! it's fat! and taking up space that I could have used for canvas!)

And I'm pretty sure my other dockers also had their minimum size increased although not 100%.

But I see you guys have been breaking your backs working on Krita over the past month or so that I've been out of it, good job! I'm really liking some of these changes (although if I were to point at any one change that I absolutely hate, it's how you put more stuff into the main toolbar instead of just removing it entirely as it is the most redundant interface feature in the entire program, I think there was already a thread about this somewhere... the new icons in it are also really ugly which doesn't make it better)

That's a bug due to the merge of the multi-window branch.

For the toolbox, try deleting your krita/workspaces folder after making a backup and on a restart of Krita, select some default workspace. It worked for me.

This bug is fixed now.
