There is same problem with ST2, ST3 that is sidebar folder status not saved after ST closed.
I mean tree structure (show-hide) status.
I often work with big projects that have many sub folders. For each times i open ST, i must re-open sub folders again and again. The thing take me more time >"<
I think there have many developers have same problem with me
I have searched many times for the problem, some users have ask the same question since May 2013 (in the forum and sublime.userecho), but now it's still not resolved
I would like to see the feature or some Sidebar's API will come with next build.
would like ST's developers see the thread
Sorry my english is not good
