Creating a collage seems to not be running in the background
When creating a new collage, it appears that the main thread halts until the image creation and saving process is finished. Creating a background process for these operations should resolve the issue
The collage feature is currently "half-implemented", where it was an unfinished feature that was brought forward to this version of the program. In other words, it's not a fully complete feature yet, but in time it will be easier to use and interact with, including not mysteriously locking up the main thread in the background.
The issue seems to be caused by this line : https://github.com/TagStudioDev/TagStudio/blob/ea8d954548579d107b3efc7ab2fdedf61bc2afcd/tagstudio/src/qt/ts_qt.py#L1148 Removing it resolves the issue of halting the main app thread , ther's still lag when the image file is saved
would be nice to use if was made to at least function properly in this hard coded state (although i would probably just use it as a funny image generator due to how little pixels are given to each image)
(also poking this issue cause its months old and don't want it to be forgotten tbh)
