It would be nice if the Uses clause manager would allow you to have one unit per line so you could easily comment out a unit and verify the project still compiles when removing obsolete dependencies. Perhaps a region could be employed to house user added/managed units vs those the IDE manages as they do tend to get mixed together in the Interface section.
Some people have even suggested that if units were sorted such that RTL/VCL/FMX units would be grouped together, it would make managing developer added units in the Interface section much easier.
