I am sharing here one idea that would make the New Model Experience even better than it is now:
Automatic formula indentation / keeping white spaces and new line hits in formula text
It would be quite nice to be able to keep the formulas more friendly-looking and let devs to work with them easier.
Colours in formulas made reading them much better than in classic experience but i believe that at least some of you would agree that comparing it to programming text editors we are still on a half way to have really nice solution.
There are several ways to achieve that (mentioned above) and if there would be a plan for implementation then i think that master anaplanners might be surveyed which to pick.
By the way- there was a browser extension that supposed to do the magic in old experience, just FYI (not perfect but worked pretty well)
Cheers!
