I'm definitely of the opinion that a new era of personalized software is emerging. I'm not sure that UI is long for this world as agent harnesses become the primary interface people use. That being said, i.e., I would like to have custom pages / layout in Argo because what is there is terrible (devops doesn't do design / UX well)
You might want to attack this market from the other side. Companies (providers) like control too much and users are the ones with the real pain. I don't want to have to wait for them to add something like Vendo to their roadmap and hope it gets built one day. "Now's the time, the time is now!" ~ LZ
