It would be much simpler to have a button that you could click to affect the current, all tracks or switch off.
Select all is Ctrl-A, none is Ctrl+Shift+A, and current is click the track number. Selecting a track number selects all the clips in the track. You can also sweep through track numbers in the track header to select some or all tracks, and if you already have a time selection established by having swept in the timeline or selected a clip, you can hold Ctrl as you sweep or click to add tracks to that selection without altering the time range.
I've heard of ripple editing, but do not know all the ins and outs of how it's implemented in other DAWs. Clearly SONAR needs some extra clicks to accomplish some of what you want. The benefit is more flexibility, and I think it will seem less cumbersome once your learn all the keyboard shortcuts, modifiers and mouse gestures available.
The workflow in every program is different, and you tend to come to rely on things that a program does well, and avoid things that it doesn't. SONAR's awkwardness in some areas is well known. But, likewise, I'm sure SONAR can do some things with a click or two that are much more cumbersome or impossible to do in other DAWs.
