Frequently I need to make edits to one of the files (video/audio/image) in my Shotcut project via other software. Is there a way to then get Shotcut to reload just the new version of the file from source without saving my work, exiting Shotcut, and then reopening the project?
Also, is there a way to change the source name or location of the file (e.g. …/videos/video101v02.mp4 to …/videos/video101v03.mp4)?
The only way is to Save (or File > Backup and Save) and then reopen the project (most convenient is to use Recent). You do not need to use Close, New, or restart Shotcut.

A few ways:
Edit the XML of the .mlt file in a text editor.
Move either the source file out of the way or rename it and use the Missing Files dialog that appears when you open a project with missing files to resolve it.
Open the new file in the Source player, set the in point as needed if video or audio, and use the Replace function in the Timeline.
