Due to being a beta tester of @SkepticMystic’s breadcrumbs plugin, I had to install new versions rather frequently. The process was too manual for my taste, so I made a shell script. (find the repo here)
The script preserves your settings.
I only tested it with his plugin, but for other plugins it should also work; you may need to make some adjustments (apart from the variables). (If the folder name is different from the repo name, for example; it also expects a zip file and not three separate files)
For Windows users: running it in WSL(2) should work.
