The most recent commit to the repo begins the implementation of a new feature that I am quite excited about. I've added a list of macros that can be saved in your phone and then executed whenever you want at the click of a button.
To access the macros long press on the serial text output (make sure you enter REPL first!) after you long press you'll see a list of your existing macros (none by default). You can create a new macro, and choose a name for it. Once it's in the list you can edit the macro and add some code to it. Press the save button to save the macro file to the internal storage in your phone. Press the run button on a macro to execute it in the REPL.
I've not updated the APK in the repo yet, so if you want a sneak peak of this feature you'll have to clone the repo and built the app yourself. Once the user interface is a bit better and some more of the kinks are ironed out I'll make a new APK for the repo.
Also we should be launching with a version on the Play Store soon so it will be easier to install the app for new users.
