The Custom Keyboard Is the Worst to Maintain

Every input is controlled there. Every time you add a zero, it's controlled because for example, here if you do something like this and you want to add a zero here, it shouldn't add one at the end. And also if you are here and you type a digit, it should set up the next one and not add a new one in the middle. All of this is done 100% manually. So every time it just has a text with a selection and the next one is something different. It has some behavior and everything is tested. But there's a lot of text, text selection issues. This is one of the biggest pain points.
