Mahou- The magic Layout Switcher

How it works

Mahou works completely different from other Layout Swtichers, it switches not by next layout, but by specified in settings layouts.
Even selected text switches just between selected layouts, though if you liked cycling through, starting from v1.0.2.9 there is Cycle Mode.
Mahou requires .Net 4.5 or greater to work properly. Begining from v1.4.3.9 error when running on .Net 4.0 were fixed.
Features

How to use:

To convert selection hit Scroll when select text.
To convert input hit Pause when typing.
To convert line hit Shift+Pause.
To change layout by one key press CapsLock.
Starting from v1.0.4.4 in Convert selection unrecognized text by all selected layout in settings (example: ?) just rewrites.
