Some small but important UI improvements

[C-Fu]

I sincerely believe this is THE ssh client for Windows to get. Even in linux this client is better than most out there, and I think I've tried quite a lot of other clients to know.

That said, some small UI improvements that I think can make it better.

1. When you click on Files, pressing down would go straight into browsing the directories. Current behaviour: just viewing the current directory, still need to click using the mouse
2. Clicking Terminal would go straight into the caret location of the current terminal. Current behaviour: still need to click inside the terminal to start typing
3. Double-clicking on some/all files would open the internal editor. Maybe...... selectively open any non-binary file with internal editor? Current behaviour: double-clicking opens the system's text editor of choice. Need to right click>open with>internal editor
4. Dark theme for the file manager 5. [BIG ONE] Ctrl or Shift + Tab moves between Files, Terminal, etc.

Thanks!

6. Scrollbar in Terminal - HUGELY IMPORTANT!

Can't really see the scrollbar IMO

I guess the app is dead. Anybody wanna fork it and continue development?
