We see regular complaints from users about the management of VCs - - especially confusion resulting when someone wants to delete the (M)aster version and replace it with one of its VCs.
I suggest a new option in the context-menu, when one Right-Clicks on a VC … with option allowing;
“Replace Master and delete this Virtual Copy” - - which then does what it says.
I reckon this might alleviate a lot of confusion - - and even make it easier for the veterans out there too.
a better solution was already worked out in the other thread, yet spread over several postings: Allow free and static naming of virtual copies. Besides naming, there is (currently) no technical difference between virtual copies so a “master” it no more than a VC not causing a suffix on the exported image.
