Thank you!
I just added a feature where you can select whichever icon you want by editing the text file in .config/prideicon/lastselected
Just make it one line of text with the absolute path to the icon (.png on Linux, .ico on Windows) then restart the program.
There are different screen sizes. Your monitor isn’t the standard universal size of every other monitor, some are larger and some are smaller. Your phone isn’t the same width and height as every other phone. The website will look different on different devices.
