There is a bunch of files to open, and if every year I am going to have to re-open my workspaces that is going to be painful. Especially due to how many projects I have going. My workspace is not going to change between jumping Komodo versions or between reopening a project where I left off.
If we can get search working on remote projects, it would probably account for 90% of my needs for maintaining workspaces. But as-is, I need to maintain my workspaces for global project search to work.
