[TxMt] Hide file browser not persisting across tabs anymore

Hi,

I’m using Textmate on a 24” monitor in portrait mode. I often hide the file browser as it takes quite some screen real estate in portrait mode. Unfortunately, since the newest automatic 'nightly build’ update (2.0-alpha.9505), when I change to another tab, the file browser reappears again rather than staying hidden. Is there a setting or another way to avoid this happening?

Or, lacking that, is there a way to downgrade to the previous version?

Off topic: is there a open bug list available for textmate 2? I don’t see any on github.

Off topic 2: are there any tools available to search in the textmate mailing list archive, short of going manually through each month’s archive?

Thanks and regards, Bas
