Add settings.json option for turning jumplist population on and off

[bavis-m]

Description of the new feature/enhancement

I already use my own custom jumplist editor to put windows terminal profiles (just certain ones) into the jumplist for windows terminal, as well as other software, and other invocations of WT that are more complicated than just loading a profile. It would be nice in this version to be able to turn off the new built-in jumplist creation so my jumplist items don't get overwritten. Plus, I just don't need a jumplist for every profile in addition to the ones I've already manually set up.

This could be either a global "enableJumplist": false option, or a per-profile "hiddenInJumplist": false setting, which would allow users to customise the jumplist without a 3rd party editor.

As long as "hiddenInJumplist" could go in the "defaults" profile section, and would not cause windows terminal to set an empty jumplist, that would work for me. The problem with that being, if someone had a profile in the jumplist, then at some point hid all their profiles from the jumplist, it would never set the empty jumplist they wanted. That's the reason why I think it would be valuable to have a flag that prevented any jumplist setting (your first option fits the bill there).

This isn't a terrible idea, but maybe it's something we should combine with #1571, rather than making it a part of each profile. Maybe in the future we'll want the customized new tab menu to appear in the jumplist rather than just the list of profiles.

Though, I suppose most actions won't really make sense from the jumplist, when they might in the new tab dropdown. Plus, I don't think we can do folders in the jumplist.

Maybe I've convinced myself that this should be a part of the profile :P

I'll keep this one open as a discussion. I think we need to land on a design first. 😄
