Multiple projects in one

I need some advice on creating one master project that can hold multiple projects in it. I was inspired by an old four-track tape i found, which had a bunch of ideas and demos from a particular time period. These days, i usually start a new folder for each burst of creativity, which i proceed to fill with tons of random projects (each in their own folder). The problem is when i want to skim through all the ideas for myself or someone else to listen to (you know those late night, been drinking, show off all your new work to your friends sessions), that it's kind of a pain opening and closing all those seperate projects (especially if only to find one stupid guitar part on half of them.) I'm envisioning one huge project(a giant palette if you will), full of random smaller projects, each in their own track folder. I know you can mute tracks, make track effects inactive, and hide tracks from the track pane, but does that completely eliminate them from CPU use? Could i, in theory, have thousands of tracks like that, and just activate certain ones for certain projects? Is that even the best way? It would benefit in that you could at least see it to know if it was something small before unmting it, and then listen before turning on the effects. Any ideas?

Search the forum for "PiP" or "Project in project" or "ReaParts".

thanks for the response! while reading into your suggestion, I realized the things that i really need are just options for a track folder which might already exist, such as 'selecting track folder selects all tracks within folder'. I haven't been able to find that, and it would allow me to set one macro for 'hiding all tracks in track pane, muting all tracks, and setting all effects offline.' I still don't know whether or not those tracks would require some CPU or not, even when muted, hidden, and set offline

Might be not what you wanted but :) You can put tracks in a folder, place an empty item on "parent" folder track which is the same length as the items in the "child" foldered tracks then use the group item feature to make all items move as one. Empty items can also contain a image or text which helps. We don't have proper folder overviews like cubase yet but i'm sure we will :)

Tricky PIP but easy and functional
