I've been using Squid for notes, which, generally speaking, seems to work well with nice features, but I still struggle to use the pen properly and have full palm rejection, smooth lines, etc.There are some apps one can use as spen replacement apps. At first you need NoteBuddy and CM Spen Addon, both are free apps and available in googles playstore. For notes I commend Squid, LectureNotes and Google Keep with Sketch addon and for drawing I'm using Handraw, AutoSketch, Skeido and Sketch3D, but these a more for technical drawings apart from Handraw. But there are many more spen compatible drawing apps available.
There are also apps available which brings full spen functionallity and more to CM roms, like GMD Spen control. An AirCommand replacement app was banned from playstore and is only available as direct download. But I don't remember the link, sorry! Both are paid apps by the way.
Do these apps bring that functionality back of the spen?
Is this the AirCommand app you were referring to - http://www.emandt.net/Android/SPenCommand/Website/
Any feedback on how this works with current ROMs for our P600?
