Switch between files with related extensions. For instance, .cpp (C++ source), .inl (C++ inline files) and .h (headers).
Missing files will be skipped over silently, making it easy to support extra languages or unusual extensions (e.g. there are various conventions for C++ files).
This is similar to a number of other extensions that toggle between header and source, but can support cycles of more than two files, which is useful for C++ inline files.
Hit 'CTRL+7' ('Cmd+7' on Mac) to iterate through the different extensions of the same root file. If there are no other matching files, you'll get a notification.
None, though this is my first VSCode extension. Caveat emptor.
Don't be shy!
Bugfix: now iterates in the current editor window rather than the leftmost one.
