Would love to have a V3 like usermanager that can run on newer firmware. V4 + usermanager is just too complex for our scenario. Currently have limited hardware I can use as firmware has to be downgraded to V3.30. This would also allow me to use a cloud router. I know I could use a radius server but we love the simplicity of UM V3 and it does exactly what we want the way we want it to out of the box. I can't be the only one.
