Hello,
it would be appreciated if the folding functionality of SharpDevelop could be more like in the IDE "IntelliJ IDEA". See image: https://www.jetbrains.com/idea/
First there are two arrow-shaped fold buttons per foldable element, i.e., also one at its bottom.
Second: SharpDevelop has the problem of opening closed elements while you write. It should remember which folds were closed when it has to process the file again (context-based?).
What do you think?
