Any regular users of the Adventure Journal?

Believe it or not this is this is the feature that is tilting me towards Coros over a Garmin (even though current sales are very tempting). My use case for this watch is an upcoming 5 month thru hike. I have tried journaling on similar trips before but the last thing I want to do after hiking for 12 hours straight is sit down and journal. My hope is that with the Adventure journal it will be much more manageable because I can just press a button while still walking and journal throughout the day.

So I guess my question is does how good is the adventure journal at journaling? Is it as convenient as it looks? Also I would like to keep these journal entries for a long time, is there a way to export them or am I tied to coros apps and if they ever lose support I lose access to my journals?
