When putting my .noesis file into my game frontend root folder (the place it seems it needs to be to be able to browse and find the projects .xaml files, as these are distributed in different namespaces) it takes a very long time (like 30 sec) the first time I click to pick an image for an image brush. This happens only once after studio is launched, after which I assume it is cached, because then it works fast.

I would guess the long time is many folders, in particular I do have my visual studio Release and Debug folders here and since I have set up that my .pngs are copied when I build I also get the list of possible .png's polluted with incorrect paths to temporary folders.

To me it seems a good solution would be to be able to direct studio from what folder (or folders) it should search for .pngs in, that way I could point it to my Assets folder and that would stop it from showing me .png's from temporary folders and hopefully also be much faster.

I guess, changing my Debug and Release paths in Visual Studio could be a workaround for the "pollution"-issue, but even when I try to launch after having cleaned those folders away, it is still slow.
