Video Versions and a gliche?



I’m getting comfortable with video versions (but I keep most alt versions in the extras folder and manually path them in the manager). I guess I have a fairly customized set up with nodes & smart playlists. Pursuing some of my deadwood, backspace in & out of various library collections (I think, I was tired), I ran into the usual pick a category defualt page.. (without my customization’s) but at the bottom it had an icon for ‘Versions’ a bit surprised, I opened it to find versions listing, clicked on Imax.. and all my Imax opened in view… backed-out and tried others, yup they all showed. With this I promptly decided to use this easy to use versions as a sneaky way to categorize.. oops, forgot to favourite the versions icon, and have been unable to every find it again!

Did I discover a new way to categorize? or was this just a gliche. If it’s on the table… where can I change version selections, so I can add e.g. colorized or B&W etc. (edit)  Never mind found it in the manager.
