Image Gallery - more then one library / widget template

I was goingt to ask this on Suggestions but the 'new thread' button is missing over there :-(

This might be two dumb questions if I simply missed it or two suggestions.

a) I would like to choose more then one library to be displayed with an image library widget
b) you can edit the lightbox template for example but I dont seem to be able to switch templates to my own like I can do with other widget.

Am I missing these points.

1) If not can Telerik add them to suggestions
2) what happens if I can not change the lightbox widget to be used. Made changes on next update if Telerik might change some wiget out of the box functionallity.
