Collections feature in Live 10 is a HUGE time saver and a bless for organizising stuff below one category.
but only 7 categories feels to narrow for me. If I could even save a Collection set for making room on future projects, and everytime I wished I could recall it (import from a project or a xml file, etc.)
Other alternative could be the following: collections' scope is not global, but inside project . So the user can make collections tailored on each new project/session. Collections are importable to one project to another via Live's Browser (drag & drop).
Please Mr Ableton consider this
