+1 from me on this.
CF6 is a far easier product to work with than CF7.
I use Ctrl-F shortcuts quite a lot as I work to quickly find the tool I need. This works in CF6, but the concept of hiding the tools in CF7 until you search for them is painful and very time consuming.
As with other contributors, I'd happily pay for new licences to have CF6 operational in Joomla 4.
