Shrink and expand is fantastic but let’s be honest it’s a tad limited. I believe the addition of a dedicated resize function to advanced edit would be most welcome.
Here’s a quick mockup of what the new interface might look like.

This would work really well in conjunction with the ability in advanced editor to choose resizing of selection / track / pattern etc.
What are your thoughts on how it could look/function?
Comes close?
Yeah dblue’s tool does help vV, I got credit for the idea 
but I prefer built in functions.
My idea here is more flexible because it works with different selections plus it’d be more stable as a native feature.
I’m not a big fan of offloading functionality into 3rd party tools that have to be found especially when they would be very welcomed as standard features and are such in comparable software.
I agree with that if it is also the case. (And i definitely agree dBlue should really put his good stuf on the general tools page instead of letting them get lost in the tools forum 
)
But the forest of native desires is usually so dense that it can get hard sometimes to distinguish a generic desire from a personal one.
Yep it’s in Live, Logic Pro, Cubase etc. and tends to work the same way in all of them.
Here’s what Ableton calls MDI Note Stretch.
