In a document that has multiple guides for various texts and/or objects, the guides appear in their position order which is already helpful. However, the only way to know what guide goes with what objects or texts is to actually move the guide since when I click on the guide it is not highlighted in the Guide Manger. It appears that one must remember what guide position number goes with what set of objects or texts, and when there are many guide that becomes quite a challenge..
Perhaps it is expecting too much, but is there any way that the user could name each guide or set of guides in order to identify it for quick reference, such as your light print reminders in the layer panel telling us what the layer is following the name we can give to the layer? It would also be helpful to be able to sort layers according to their use on the page. Just dreaming....
