The 3.5mm adapter is simply horrible. It sticks out like a sore thumb, and I have to use a 3rd party case to mount it on a tripod. The better thing to do is create a mount, just like the wireless adapter. After all - I cannot use the wireless AND the microphone anyway. This way, the audio plug doesn't stick out 25mm (1 inch).

Agree.
The 3.5mm audio jack is such a bad design.

Can't hope too much though.
Waterproof case isn't released for 6 months. Extension Rod as well.
Even if they decide to release it, I think need around 6 months, which I think they already thought of OP 2 already.

Heck, even an osmo action is released already.

I didn't even get around to check this feature out.  Guess I'll be scouring the web for any hopeful resolves.
