Hi kbin users. @shazbot has been working on resolving iOS issues today, and I can tell you that it now works. I’m just a user and know nothing of the scripting these people are doing. I just understand plug and play, along with various settings of apps on my phone. So, for all iOS users you can now enjoy KES settings.
Edit: Follow the directions to get Userscripts and KES here. Make sure to install Userscripts first, set its directory for storing scripts, and then when you open KES and see all the texts press the Aa and extension symbols on your safari url bar. Go to Userscripts and load that.
Are you beta on iOS? Like @shazbot stated, go into the hamburger menu from left side top and look for the wrench in there. When they first got it working, it could be hidden depending on color scheme chosen inside kbin settings, but they fixed that.
