Like you, I was/am a big fan of Actiontiles. I was one of the 1st to sign up for Actiontiles for Hubitat when it was released. I made it clear that I would gladly purchase a license when it went from beta to full release. However, things got delayed and others who were not already sold on Actiontiles moved on to other dashboards, including the one that comes with Hubitat.
Unfortunately, the plans for Hubitat integration came to a halt when one of the founding members of the Actiontiles group passed away. That generated some legal issues as well as reduced the staff for support and development. Thus, development Actiontiles for Hubitat took a back seat. The platform seems to work quite well as is and Actiontiles continues to support Hubitat users under the beta program, but it is evident that no improvements are likely to be made.
I have no plans to terminate use of Actiontiles as all my panels are set up and working as needed. I am just hoping that Actiontiles does not quite support for Hubitat as I would have to recreate all my dashboards. That would be a pain.
