1) It is not known. I found this:
https://www.owdeutschland.org/blog/aktuelles-zum-status-von-oxwall
April of last year that gave hope that something would be published, but a year later we see that it has not been like that.
However, there are many updates on GitHub that are very interesting but require a little more technical knowledge than usual to download and install them. The developers have all gone to SkaDate and those of us who are not customers have no access, not even being developers of OxWall plugins.
The outlook is not good and that is why it is interesting versions - more or less legal - of OxWall as Chamial, or those that seem abandoned: OxWallPlus, OxwallAmerica and OwEngine.
2) Some plugins if and others do not, there are many plugins of developers who abandoned OxWall that remain in the store that do not work, or do not work well, and that discredits the store and OxWall. I think the "rules" of the store is missing a very important, and if a developer disappears for a long time, their plugins passed into the public domain and others could continue to develop.
3) In the store there is one, it has been updated recently.
4) I do not know, my website is for adults and it is closed to any interaction with other networks. I have not studied these subjects.
5) Progress is being made in this direction, but at turtle speed. The development tools for APP are very expensive so I do not think we never have an APP. The browser version of OxWall does not like the users or plugin developers, from my point of view it is a bad adaptation. OxWall deserved a better mobile design ... but when it was done the brain drain had already started. There are things in the store based on PWA, they are expensive and complex and nobody knows how they are used. I bought one of them, I have not known how to use it and I have left it as impossible. Maybe it's my fault for not speaking English, for too summarized instructions that Google translates badly, and links to websites that are too technical and need many hours of study to be able to do something.
I will continue to make plugins but I do them for my website that is profitable. I put up for sale those that I think can be useful, few, because I entertain too much in that they are perfect and that few people appreciate it. You make a 5-10 USD plugin that in one weekend you have it done and it sells well, make one for 30-40 USD very complex that requires months of work and checks and one or two are sold.
My modifications to other plugins can not be put on sale, and my modifications to the OxWall kernel makes some plugins incompatible, so I do not publish them either.
I do not know if OxWall is recommendable or not to start a new website because I do not know other platforms, I have always been with OxWall and now that I know it thoroughly I will not change.
