There is some good ideas to be sure ... also some that are absolutely horrible. :-/
But most of it looks like fine work, or concepts for moding comunity!
Especialy that UI changes ...
(BTW your second link is not working curently, not sure why.)

Now few notes:
- Personaly i kinda like that non-spell casters have abilities in hotbar, just as spell casters have ... otherwise they would be awfully empty for fighters. :-/

- I kinda like that spellcasting option ... but cant shake the feeling that trying to hit small arrow is not best way to get to adwanced spell levels. :-/
I still believe that current version would be perfectly useable, when combined with option to give both spells with certain levels (Mage armor lvl1, click and cast) to your bar, aswell as spells containing all levels in popup menu. :-/

- That "following" concept is interesting, as long as you play with protagonist only ... but it seem potentialy chaotic if you change your characters ...
If you want to create 3 groups, where Gale is allone, Tav is allone, and Shadow with Laezel is together ... how would you do that? It seem to me that Shadow would follow Laezel just until you change your character, then she abandon her post, just bcs she now start to follow someone else. :-/ Also managing who is suppose to follow who with every character in particular, dont seem like smoothest solution.

- Im not quite sure how do you want to implement that battle formation, concidering how battles are started now ... but i like that March formation, wich could be also used imo.

- That dialogue dice is awesome, make them two for rolls with adwantage and i would be the happiest warlock around the sword coast. laugh

- And about those UI buttons concepts you posted, they are looking good ... maybe a little overwhelming at first, but that idea of buttons using certain resources having certain shape, so you can tell at first sight what you need ... awesome, i love it!

- HoMaM-like queue, also awesome ... loving it. :3
Im just affraid this and your party positioning is once aggain "too DoS" for many people to accept. laugh
