Can anyone tell if if there is any interesting Okcash protocol developments in the pipeline?
I dont actualy know that, but if you look at github
https://github.com/okcashpro the devs are activ

Edit: if you look at github you see that they are working on an electrum client, hopefully for android too.
There's an Android Core wallet up coming. No release date yet as the devs are busy with other things right now, but it's being worked on in parallel
An Android or IOS wallet would be the game changer for Okcash!
We are working towards that goal as well, even so:
While we agree, there are some mobile solutions already, like Coinomi (Android - Okcash integrated) with electrum technology,
https://play.google.com/store/apps/details?id=com.coinomi.wallet&hl=enor even the Discord app, where you have your own personal wallet as soon as you join where you can even stake your Okcash,
without the need of downloading the ok-blockchain, and sending to another person is as easy as doing a .tip @user Amount .
It has apps for Android and IOS, making it possible for you to have your Own OK wallets already on mobile devices,
without frying your battery or drinking your ram like every other wallet does

OK Discord (with your own personal wallet ready for use) :
