So this wasn't as easy to clear up as initially expected. I cleared all data in both browsers on my phone (chorme and firefox), I cleared all predictive text data, deleted my keyboard and reinstalled, googled "clear autocomplete android" and tried every suggestion I could find and nothing would clear the remembered data from this field. I finally uninstalled the app from my phone and reinstalled it and it finally cleared, so I posit that this autocomplete information is stored by the app itself, and not the phone's browser or user dictionary or anything else.
Looking forward to those collapsible panels and ckpool solo being a supported pool, sent a few more btc to you last night since I use this app several times a day, every day!
That's odd that it remembered the information after you uninstalled the app... It's basically a android-browser in a different shell/cover, so I assumed data was saved there.
Still working away at the new changes, I'm hoping it'll be done soon!
