Working with a large open source cart, I frequently open 3-5 or more files as I trace the code.
After working in several areas, I may have 15-20 files open.

Eventually I want to close all, but a few core files that are usually kept open.

Choice 1; Individually close a dozen or more files.
Choice 2; Close All and reload the 2,3,4 core files.
Choice 3; Close Selected [a flyout showing open files with a check box for each and one submit button]

I have looked for Choice 3 many, many times.
Its not in the version I have.
Hope to see it in a future one.
Thank you.
