Either guide groups, or being able to save guides by layer or folder. This can be improved.
What is true is that having ONE set of guides that can only be turned on and off is a sad and primitive option that Adobe can and should improve upon. Get on it people!
yeah, it would be very nice!
I suggested this long time ago, like 3-4 years ago, but still nothing....
Yep - would give them something else to put in their, at the moment only partially useful, Application Bar… A drop down menu for guide sets. Why not. Command ; could be customised to show whatever sets you want. I have absolutely no idea why buttons to show and hide Guides are not already included in the Application Bar, seems like an obvious place for it.
Other feature requests that have been made by others in relation to guides are - curved guides, diagonal guides, multicolored guides and - cusom vector shapes to guides.
I suppose the snapping-behaviour relative to non-vertical and non-horizontal guides might be a bit of a bother, but those requests sound reasonable.
