image customization and more apparent titles

[CarnelioTKS]

I use a lot of STL files and I was thinking it may be useful if you can upload an image if the file wouldn't come up with one. For example I have a STL file of a threaded bolt, I could take a screenshot of it and apply that to be the new image for that file on TagStudio. Maybe make a edit thumbnail button when left clicking on a file in TagStudio.

Something else I find could make things more friendly to use is have the title of a file displayed below the thumbnail when looking at all the files. This would allow for easier browsing when not looking for a specific file.
