Horizontal scroll bar isn't really need as the full name is displayed in the title bar.
I thought the same when first using v2 with the tuts, but it's not really needed, just my 2 cents.
All in all your v2 editor is very good
Just some feedback with issues i've come across so far:
1. When debugging and clicking on the error on the output, it takes you to that file and line.
But the current file stays red (selected), I wrote in a hearder file by mistake thinking I was in the selected file.
Maybe deselect (remove the red) when traversing?
2. Search project includes the ethenel library headers.
This is a pain, because I just want it to search my project files.
I know open file would do the same thing if I opened all files, but that's a pain to do every time.
Maybe add another button Current Project and rename Project to project & libs?
3. In code editor, how do I close a file once opened? ie lib header
Maybe this can be done within the openfile list (v1 alt 3)?
4. clean/clean all should have output cleared & confirmations
5. the Tash can is very close to the top right of the code area, i've clicked the trash button by mistake a few times.
6.with a single application project, do a search for object then click the build app and it says "No application select or invalid name"
