Keystone tool: Retain adjustment point positions after Capture One is closed

What problem do you see this solving?

As it is, adjustment point positions are reset when Capture One is closed. Consequently, if you've made keystone adjustments using the adjustment points, and you need to make further adjustments after Capture One has been closed, you'll have to start all over.

Making manual adjustments using the adjustment points is almost always necessary, also when using auto-keystone, as the latter, even when it does produce reasonable results, is very rarely 100% precise. Accordingly, adjustment point positions are the basis of almost all keystone adjustments, and when these positions are reset, you basically lose all the work you've done.

When was the last time you were affected by this lack of functionality, or specific tool?

I'm affected by this every time I use the keystone tool, which I do often.
