Description of the new feature/enhancement

The "compact" tab width mode hides inactive tab titles and only shows icons for them. With multiple tabs of a same profile, it's hard to tell the difference without a descriptive title (which is controllable from the shell).

A "compact" thing means to pack enough information into a small space, often in an unattractive way. A workaround is to use a non-existent "icon" target for all profiles in settings.json, but that's hacky, and doesn't save enough space as expected. Let's compare Terminal and ConEmu, both snapped to the right half side of my screen:

Thus I propose a new tab width mode, say "textOnly", that hides icons (even for the active tab) and shows compact titles only.
