Enhance_Hover_On_Var.png

While debugging I'm rather frequently using window which appears when hovering mouse over some variable, however I see number of usability issues there.

1. The major one - it appears at some fixed position and is not resizable, i cannot make it larger to view content of huge list/dictionary easier.

2. It is not movable - it is not possible to re-arrange the window to see at once content of the debug window and part of the screen that is currently covered by the window

3. The last thing - it also relates to Watch/Varialbes pane - in some conditions it is better to present variables in simple tree view (not tabular view) - this way it is easier to view multiple lengthy expressions.

See screenshots for more details.
