I implement new functionality as it fits my personal priorities and I don't discuss the todo list publicly.
As for follow me: FollowMe is at the very top of the todo list.
But: Nobody ever came up with any idea how to make this work reliably with what
Tello has to offer. So far I have not seen any approach to handle the issues with missing GPS and compass, nor the problems associated with a visual follow me that are nicely shown in aTelloPilot.
That said I am currently experimenting with some pretty ground breaking functionality. I've played with an idea for a couple of months already but I never found the time to test it. Now that TelloFpv is stable and pretty functionality rich I think its time to get this one rolling.
If it works it will be released as a paid add-on to TelloFpv, unlocking a few pretty interesting functions. If it does not work to my expectations I just wasted over a week of dev time on a stupid idea. Either way I will let you know in a few days. I need a few days of good weather to test outdoors.
