RapidEERapid Environment Editor
Edit Windows environment variables with instant error checking and convenient handling of long values.
RapidEE
10.0
The old version was becoming harder and harder to maintain — third-party libraries were no longer updated and the development environment was outdated. So RapidEE was rewritten from scratch in C#/.NET 10. The move to version 10.x aptly symbolized such a big change. Sorry for the long wait, I hope the result will be faster, more stable, and much more convenient.

Error checking
Automatic validation of paths and file names, with problems highlighted in real time.
Drag-and-drop
Drag values to reorder them within a variable.
Content assist
Hints next to the cursor, accepted with Tab, with cyclic candidate switching. Separate modes for paths, files, and variable names.
