From the point of view of a developer, like all of us here are, I believe that a remote assistance system of this type would be a little gem.
Each of us needs a tool of this type
Furthermore, if it also offers capabilities that others do not have, such as installing new apps or updating existing apps (neither team Viewer nor Anydesk have this feature), it would be a really valuable tool.
I hope you get to complete it, so you can sell many
And I hope to get to see it, because such a tool would be really useful to me
