I'm working on an Experience right now and had been using a window for some information. After fiddling with it for a bit, I decided it would be better as a panel in a page, instead.
I moved the relevant element to my pending list, switched to look at the pages, and found that it was not in the pending list.
As a result, I now have to rebuild, when I could have just pulled it out of pending.
Please let windows and pages share pending lists to make re-organizing more easy.
