It would be nice to have a simple options list to enable/disable windows that DeModal touches so users can turn off the windows DeModal affects.

Make extensible to later be able to also leave windows in "managed" mode and just enable temporary repositioning (ala BlizzMove).

+1 great idea - i like having control of what the addon does and doesnt
Along with this, addon should not move any frames by default when user installs it
Currently some frames are relocated by default
They should be in default position technically until enabled and moved by the user :)
