Thanks for the tipper, literally the only buttons I haven't tried HAHAHA!
As a fellow software developer, you have my full support on this project. I'm not going to give you tips on features you could implement, a solid codebase first is the step for an even cleaner development and improvement.
You have my full sustain, both emotional and in the small payment for the software. Not much, but I don't regret a cent. Keep on keeping on!
