Hey there!
Yes, I finally made it!
The projects have been added to SkEditor+.
Well, almost. For now, I decided to do it like with the code completion - meaning that projects are not enabled by default, but you can enable them with an add-on.

Any other changes?
I only remember two things besides the projects that I did, not sure if there was anything else:

• I fixed the bug #47
• I cleaned up the code (it should be more readable and maybe even slightly more efficient, but it's not the end - I'll keep improving it)

Just a reminder that to install the add-on, you need to download the .dll file below and place it in the folder %appdata%\SkEditor Plus\Addons (you can easily open it in Settings -> Addons -> Open).
