two suggestions

I got two interesting ideas while using kdenlive:

The first one is the possibility of exporting the entire kdenlive project (including all media) as an compressed file, so you can just take that file to another computer and continue working on it.

The other idea is to group two or more tracks as a grouped track (that is just for better space usage), the grouped track can be ungrouped at any time.

Currently, it appears that the EDL files (xxx.kdenlive) files contain a mix of both absolute paths and paths that are relative to the user's home directory. Absolute path names give more flexibility of where things can be located, but if there was an option to use only relative path names, then it would be possible to just archive your working directory (assuming you thought ahead and put all of your source material in its own directory tree) and your EDL file and move them over to another computer.
