Huge huge thanks... That menubar business has been irking me for ages under Linux.
Yes, there are a few issues...
1. Show menu state is preserved properly between sublime restarts when menu is hidden in distraction free (Shift+F11) mode
But not when menu is hidden in windowed or full-screen (F11) mode.
2. Menu reappears when using Ctrl+Mousewheel to change font size. I'm almost reluctant to mention this, since it's quite handy; it gets me somewhere near Alt-to-bring-up-hidden-menu in windows. However the menu appears incorrectly, overlaying the top x pixels of the editor view. This occludes the tab-bar in normal mode and the top line of text in distraction free mode. Plus sublime's "show menu" state is wrong, it still thinks the menu is hidden.
Hopefully the Alt behaviour is coming in Linux
3. When menu is hidden, certain actions cause graphical glitches in normal and full-screen (F11) mode. For example hitting Ctrl+O to open a file.
Again, thanks for hearing our pleas - loving being distraction free on Linux laptops at last!
