sorry, but i'm playing last weeks with portainer, and there are things that i can do with it (s useful to monitor existing containers) but i can't create new containers.
For example, I can't create a macVlan from portainer webGUI (need to do from CLI).
eG: I can't run pihole image or airsonic image ( i do not know how to create volumes for /config or other needs).
Portainer WEBGUI only permit preconfigured volumes, and when go to volumes I do not know hot to create one for /media etc..
Perhaps if portainer is the goal for 5.0 series, someone need to start to use and post some guides like ones exist for actual docker GUI that is really usable and easy to understand.
what? I think you need to do it again, or pull the latest or if you want develop. All those features you mentioned are there, been there for a long time...pretty sure. The ability to update the image and “modify” containers is on develop tag.
There is no goal for 5 series, portainer is a web app that anyone that uses docker can use, it has 20 times more features than the plugin, is actively maintained and is fast.
They have a readthedocs web wiki.
As for volumes, yes the browse folder (host side) will be lost, don’t think that’s terrible, and not a good reason to keep maintaining the plugin.
