It is SO helpful that MMV allows annotations linked to individual modules. To build on that, I often find myself wishing there was a module that was purely for annotations. Something that doesn't affect the Magic Window in any way, but is just there in the GUI for organizational purposes.
(I know you could just use any given module and not have it actually affect the Magic window, but a designated "Annotation" module would be cleaner).
Would be nice to
1) Just put floating notes for yourself/others in the GUI wherever you want. No inputs or outputs to the module.
2) Link the Annotation module in-stream with your flow. Maybe to give notes like "Everything before here is blah blah, but everything after this point is blah blah).
