I'm willing to put down $5 for Clickteam to make this update. If you've decided to embark on a large-scale project, you're probably spending most of your time playing hide-and-seek with the Group List. I think one of the main reasons you don't see many A+ titled made in MMF is how inefficient it becomes to edit your code once the project grows large. It seems Clickteam are very focussed on bringing new users to the software, but this simple fix would ensure advanced users can still program with some degree of efficiency.
Two major improvements that could save weeks of development time:
1) The number on the left means NOTHING. It could be revised to reflect the line of code that the group rests on, making it easier to find that group you're working in.
2) The group list doesn't reflect the nested nature of groups. This makes finding the group you're looking for even more taxing. By indenting the list, finding groups becomes much simpler.
Hopefully other users will support this and pledge a bit of money to make it happen.
