Hello, my English is not good, I can only communicate through Google Translate, I hope you can understand what I mean.
I hope that the author can add thumbnail options for recent projects. If the project is too much, it will be very troublesome to find.
Some GIF diagrams are continuous. If you are clever before and after, you can't see where the beginning is and where it ends. But it is not easy to create such a GIF map. I have done it once and need to filter one frame by one frame. I hope there is a more convenient method.
My approach is to select a frame, then mark the similar frame, then delete the marked frame and the following frame, leaving the loop.
I have not learned programming, so the problem may be naive, I hope you can understand, but I like your software very much, I hope the author and software will get better and better in the future.

Mocking something up based on what I think the poster is suggesting:
Steps:
Change: now in addition to date, time, and frames, there's also a first frame.

You could get fancy and have the GIF auto-play when you hover the mouse over the project.
The idea of a mouse hover is great.
Why not add a button that displays thumbnails and details like other software.

Yeah makes sense - good suggestion.
There's also a third way of doing this:
Only display the thumbnail when the row is selected. This is also easy to implement.
