Modifier key + mouse to exclusively solo, mute or select track targets, and deselect all other tracks with one click.

Often a feature in DAWs, it would be nice to be able to hold a modifer key (control, shift, alt/option, command/windows key etc), and left mouse click on a solo, mute, visibility or track target on timeline, and have just the one button be exclusively selected. So if 4 tracks are already soloed or muted, modify key+left click to solo just that specific track. This allows you to quickly switch soloing and track targeting to one track with one click rather than having to shift click, deselct all, and then click agin to select just the track you need.

This is useful if you have multiple audio or video track layers and just want to solo a specific track quickly with one click. Of course all of the above can be applied to track targetting, muting and the visibility button (for video). This would save a lot of time and clicking when comparing tracks for take selection or to check a specific track in isolation.
