What about the (good old) FILE INFO window? Can it be docked??

Don't think you can but there is a "description" box in the track section of the inspector that may be suitable. That can then be called and hidden via the "I" key cluster.

Yeah there's a few windows that are missing the abilities of "Skylight" File info - staff view - event list are some that spring to mind. It'd be great if they bought those up to the level that the rest of X1 is now at.

Sadly nowadays the ability to read music seems to be a dying art. Used to be (in my day) anyone that had attended, let alone graduated, any form of higher education in music, had the skill of reading music. One thing I always used to do when composing, especially MIDI of course, was to check my work in the staff view. It would often show some glaring timing inconsistencies, or pitch errors in the harmony, and on and on, that other views would not because of the nature of written music versus piano roll, etc. I miss it a lot. It still works of course with simple MIDI, but once you get above a few tracks, and especially including audio files it becomes way too much work to be useful as a quick check. Another way I used to use it was to start all my compositions there, and then move to the piano roll to flesh out. Too much hassle now with the way it is. Sad. The File info box is even more important, and I use it on every project. I'm with you guys though and wish it were dockable so it could always be visible and useable (editable).
