When you press enter, the currently selected element(s) are brought up in notepad form in a custom form inside of osu. Once you press "OK", the map is updated. Hopefully this can be done without saving and reloading the map.
Implementing this for just the compose tab would be a little silly, so it would really be a help on the design tab for storyboards, where I use mostly notepad anyway, since the design tab doesn't allow you to input integers or even decimals (scale to exactly 0.8 for example).
I will often want to change a hitcircle by a few pixels, or a slider node by one pixel. Opening the osu file in notepad, finding the item, and editing it is slightly tedious. While I might be the only person to get a use out of the compose tab, I'm sure many others would be able to use it effectively in the design tab.
