It would be super useful if breakpoints were added to the IDE. This saves pretty much every developer from having to litter their code with console writes, and taking them out later.
A debugger is something that I see missing a lot from low code and beginner environments. For me a debugger is one of the easiest and quickest ways to understand what my code is doing. It is particularly crucial for environments that might be off the beaten path somewhat, like Anvil.
