I need to agree with two people here: Aritz and Davioware (on point 2), so basically:
1. Sometimes it only moves groups but leaves the content out of them.
2. Some clicks on the event sheet seem to select things someone would not want to select.
Also (I don't know if this is considered a "Bug"? If not, then sorry) it would be extremely helpful if one could put Layouts from one Cap into a another one. As far as I know this is at the moment only doable with the events.
People working on huge projects would find this really helpfull because there isn't the need to have the .cap of the whole Game open, instead a .cap of one particular section wich could increase the speed of editing. (Opening my 75mb .cap takes a while and previewing a Layout aswell).
Again, if this would actually be a feature and is not a bug at all, sorry.
