Is it better to start over?

[the-r3dacted]

Nobody seems to be able to make this PHP 8 compatible, and everyone calls it spaghetti code and unmaintainable.

I would be fine with making a new eBoard3, and it's probably for the best. However I want it to look nearly indistinguishable from eBoard2.

I can barely make changes to eBoard2, let alone make a full new board software. I don't think I can do it myself. If you have free time and just want to make a board, please help.
