Support Folding Custom Regions with Line Comments about brackets-code-folding

[wjapp-dev]

Also would like to be able to persist the state or at least mark the default state of a region

i.e. there are some regions I am not really interested in anymore and would like to see them closed every time I open the file, then just toggle them open when I need to.

Defining custom regions is a good idea. I remember using it a lot in visual studio. I will research how it is managed in other IDEs and see if it fits nicely with the Brackets ethos.

I have downloaded the source and developed/incorporated a foldHelper that allows for region code folding using comments, to use you just make a comment line as //Region name and then where you want it to end you refrence //Endregion for html it is similiar with when folded it still displays the entire region name line for viewing, let me know if you would like me to send the source it was rather quite simple.
