1. Like both formats, but A5 would see more use I think. The current one is great until I forget my reading glasses (which happens way too much!)
2. Never used Fate Dice, and d6/d10 would be better
3. It's useful having it limited to a couple of die types, unless there's something you would absolutely need to have another type for.
4. The general random tables / event / quest / npc and wilderness. Oooh, also the object/treasure one.
5. The Defensive, Neutral, Aggressive, Helpful table.. I'm not even sure 'how' to use it to be honest. I also don't really use the abstract icons, but that's more how my brain is wired, I'm sure most folk find it very useful.
6. Personally, I'd love some dungeon tile shapes added, even over abstract icons, for on the fly dungoneering when travelling. Particularly if staying just with fantasy genre.
7. Solo campaigns and small adventures.
8. Too many, sandbox generator (atelier clandestin), BFRPG hexcrawl supplement, Axebane's Deck of Many Dungeons,
9. Both, much prefer analog for sure, but sometimes digital is quicker to get going.
