A PATH environment variable editor written in C# and WPF
Greatly inspired by https://patheditor2.codeplex.com/
- finds non-existing directories
- path text is editable, so you can manually edit or copy-paste it
- you can "disable" an entry - it will be removed from PATH and stored in a file so you can easily reenable it
- you can drag directories into the window to add them to the list
