I have spent some time on this app. Overall, it is good but has some bugs. I know it's an initial launch so maybe it has some bugs but after solving the all bugs, I think it will be a very good open-source app.
Erxes XOS version is easier to use and uncomplicated to install also the marketplace feature is really great. I can use only plugins that meet my requirements. It's possible to develop my own plugins and I have already started to develop a new plugin.
