Code folding can be a useful feature for creating a cleaner view of the contents of a code unit. But that is only useful if the editor remembers the folding I had applied to a unit since the last time; otherwise it too tedious to fold everything. So: persist folding state.

There doesn’t seem to be a standard facility for persistent code folding in Eclipse. But if you look for ‘eclipse code folding persist’, it seems other a few other people wanted something similar. Mylin might provide a solution: http://stackoverflow.com/questions/1115653/eclipse-save-folding-on-quit. Keep an eye out for unconfirmed issue Spoofax/261 if you try it.
