Yes, sorry, i forgot to post announcement here.

Telescope 0.2.8

• Huge source code refactoring. I think around 40-60% of source code was refactored in order to improve internal logic of the application, eliminate potential bugs and make it more easy to bring enhancements in future
• It's now possible to move selection with joystick if you put following into your /etc/telescope.keys:
  
  Code:

  press(Right):  internal(selectRight)
  press(Left):   internal(selectLeft)
  press(Up):     internal(selectUp)
  press(Down):   internal(selectDown)
  press(Return): internal(switchToSelected)

• Several potential bugs was fixed
• Added a couple of config-options for one guy who tries to adopt Telescope on Ubuntu on N8x0

You just need to press Home key (F5). One with house symbol on N800 and with two overlapping squares on N810. This key usually calls native task navigator (onscreen menu with window list). After installing Telescope this button will call the graphical task switcher with thumbnails like at screenshot in first post.
