Advanced looping [WAS] Re: Testing Appreciated for 22.06

I'm taking some time for testing... And checked the advanced loop feature.

I tried to activate advanced looping (and admittedly did not read the 
whole discussion on the bug, wonder if it would be useful to have these 
discussions possibly impacting feature changes / updates in the user 
list ;-)

So as I understand correctly if advanced looping is on in preferences 
selecting the loop toggle in the transport will loop from start to the 
end of the last segment unless a loop range is defined. Correct?

This can actually be a useful feature although I'm not sure if I'd use 
it a lot (I use looping a lot to dig into specific small portions of 
pieces or to create base 'loop' / repetitive materials), but could find 
uses for it
One caveat is that I think unless the new stop at last segment feature 
(also very useful!) is toggled this should loop until the end of the 
composition. Why? One might leave one or two empty measures at the end 
e.g. to account for fading effect (reverb, delay tails), and want those 
incorporated.
I understand that probably the use case for looping over a piece is 
different and more of a 'work tool', but now we have the stop at last 
segment feature the two would be combined so if that is also turned on 
I'd keep the current behavior.

One thing I'm thinking as we're talking about looping and given this new 
feature: should we move / replicate the loop toggles in the main window 
somewhere around the transport controls we have there? while the 
transport is easy to toggle with t 't' key-press, I think it would be 
really handy (and pretty idiomatic for a sequencer) to have a button there?
I think I might use this feature more if there was a button somewhere 
(and the reason why I use a lot the segment-based loop as it's available 
anywhere there is a time ruler..)

Finally: small note for the tooltip. you can achieve what is done with 
right-click also by doing SHIFT + left click ;-)
