Automation bezier curve tension handle resolution too low, too hard to control towards top and bottom

When Studio One 3 was released I was very glad to see it finally got Bezier curves for automation. Unfortunately, the "curve tension" (deformation) is very difficult to adjust precisely towards the extremes, as shown in this animated screen capture:

As you can see, the more the curve departs from a straight line, the faster it moves for the same amount of mouse travel, resulting in very coarse adjustments near the extremes.

FL Studio and Bitwig implement a variable relationship between curve tension and mouse travel, so that the more the curve departs from a straight line, the more mouse travel is required, thus keeping the precision constant:

Reaper too:

Also, I'm glad Presonus finally have given us a reliable way to straighten Bezier curves, but IMO there was no need to devote a context menu to this single function:

Simply right-clicking the handle on the curve should straighten the curve, without the need for a second click on "Straighten curve" in the menu. Unless Presonus plan to add more stuff to that menu in a future release...

If you would like this to be improved in Studio One, please up-vote this feature request, thank you!

Ohh yeah, the resolution of the current steepness levels of the automation curves in S1 are pretty weak ...

There one more problem with Bezier curves in S1, when the curve is nearly straight, it snaps to a straight segment. If I need a curve that's nearly a straight line but still have some subtle curvature, S1 won't let me achieve that because the tension handle snaps to a straight line.

In other parts of the program Ctrl+Click resets. For example, faders, pans etc, such controls don't snap to their default position unless the user Ctrl+Clicks. The same behaviour could be used for Bezier curve tension points.

This problem applies to both automation envelopes and event fade-in / fade-out. Fades and automation envelopes seem to respond differently though, currently I find automation envelopes are jerky while fade tension can be adjusted in a more controlled fashion.

I completely agree.This is particularly painful when you have fairly steep segments (i.e., a rapid change in value); I find it almost impossible to set the curve to anything else than a square without a hefty amount of zoom involved.

This makes the workflow quite slow and clunky when you need many quick changes on your automation.

I'm still on Studio One 3, has this improved in 4? Cheers

One more thing, in Studio One the curve tension handle seems to respond equally to vertical and horizontal mouse movement. This sure can be handy BUT it S1 needs to stick with one, not constantly switch between the two. In other words, if the user starts swiping the mouse horizontally, Studio One should be clever enough to figure out that's the users's chosen direction, and ignore any y-axis movement. Conversely, if the user first starts swiping vertically, Studio One should ignore x-axis movement.
