Show tabs of files names in vertical order + alphabet sorting

[GeromTaylor]

Hello. Thanks for the tool :)

Little feedback about tabs:
When tabs are arranged in a horizontal order it is really difficult to find the one you need.
How about put them in vertical order with using alphabetically sorting?
It can be placed on left side before content window.

P.S. Sure in that case width of file editor window will be a bit smaller, but will be no any problem to find exact file you looking for.

This is a good suggestion. In fact, I had already attempted something like this earlier, but when there are more files, the standard tabbed container would arrange the tabs in multiple columns, which made it similarly difficult to identify the files. In any case, alphabetical ordering seems like an obvious improvement.

But, if it possible to provide some custom UI, then I can put here a bit tricky suggestion:

• we refuse from concept "tabs" and provide separate window with list of files name (it is border with editor window with same min_Y and max_Y),
• click on each filename should change content of editor's window,
• click on each filename is also making scrolling focus to put option in the middle of the list;

Here I created example with all functionality what I just described (try scroll down and click on any filename):

alphabetical ordering seems like an obvious improvement

But if all that I suggested above will consume a lot of time so sure that will be also good improvement.
