Also for any user thinking of switching to or starting with Kdenlive, they should know that in addition to crashing often (as reported by many users) it also does not support a relatively common video editing feature as multiple timelines. In Kdenlive, in one project/file, you are only given a single timeline to do all your editing in. You cannot nest them, combine them, there are no timelines to combine, there is only one of them.
Since this will be a dealbreaker for many users, they should know this upfront.
All respect to open source software, but for many projects using Kdenlive is just not an option as of yet.
