Default UI and Keyboard optimisation

There is a new 2.5 version (changed februar 10, 2013 evening, download newest build).
It has better UI scrollbar management (probably only one WP7 application, able to show and trace quickly full \windows\ directory). Tap and hold 'U' screen button as 'up' and 'D' as 'down' quick navigation.
This version supports hardware HTC7Pro keyboard fully!
Use hardware keys:
'0'..'9' for filesystem commander directions,
'Q' for second panel activating,
'W' for panels swapping,
'Enter' for shell direction starting,
'Space' for select/unselect item on caret position,
'keyUp' and 'keyDown' for moving up and down,
combination 'Fn'+'keyUp' and 'Fn'+'keyDown' for very quick navigation (especially in \windows\ directory),
combination 'Chr'+'keyUp' and 'Chr'+'keyDown' for moving up and down without caret position change,
combination 'Chr'+'Fn'+'keyUp' and 'Chr'+'Fn'+'keyDown' for very quick moving up and down without caret position change,

Next version will have (still in development):

Opensource plugin system (like desktop TotalCommander). First plugin will support registry keys (as 'directories' ) and values (as 'files'). Second plugin in development is FTP, where one panel will contain normal WP7 filesystem, second panel FTP site filesystem, all commander directions will works in this configuration. Third plugin will support HWND Windows, processes and threads. Another plugins you can code yourself with pre-defined plugin interface (tiles/installed/running apps, Hardware drivers, URL protocols, system services, mailboxes, SMSBox, Calls, Schedulers etc).

I examined HTC7Pro keyboard driver and it's integration into the system. I'm not sure now if bigger idiots are engineers of HTC or MS WP7 development team. The simplies keyboard functions, usual on 15 years old Nokia communicators 9110/9210/9300/9500 are reachless on HTC7Pro without very hard hacks or full keyboard driver rewriting. We can use only "non Fn modified keys" as quick shortcuts now. All top (numers+Backspace) keyboard line works with long delay.
