Currently, when editing an html file, clicking <Ctrl>Left on a jpg file name text inside <img ...>, opens a floating window where you can see the jpg image. This window has [X] and [Done] buttons to close it.
Could you add another button to rename the jpg file?
Maybe put a box with the file name that can be edited and saved?
The usefulness of this is that I often find long jpg filenames with meaningless numbers and I like to change it to a more meaningful one, but for that I have to see it in the html along with its caption where the content is explained (or even there it is called e.g. "Figure 1"). Then I have to remember that file name (e.g. capture_106_20230518132814066.jpg) to find it in the list in the left panel and change it there (e.g. figure_01.jpg).
Sincerely grateful for your work.
