Good day. Ok, I understand it needs to be running to lower the sail bundle into gallows while standing on ancorage or long motoring. As well as a mast lift for that matter.

But how much do you touch it while sailing? Needs to be in a cockpit or can remain at mast?

I see different constructions. Johana style looks like the one easily remaining at the mast base. But some more sophisticated have even two lines - to control left-right side tension while sail in use...
