I apologize for not being able to show up here for a while... My computer had a catastrophic failure several weeks ago and all my work gone. I am trying to catching up slowly... I am going to integrate more features into the wallet, stay tuned  

Basically the latest wallet has an external interface for integrated applications (the MORE icon). However I lost all my code of the original plan (screenshot shown in OP). If anyone is interested in creating some applications and glad to help, please let me know
