Here are a few ideas I have for display improvements:
1. Color blind mode-Certain things like health/mana globes, certain fishing spells and auras can be hard to distinguish for those who are color blind. Adding a color blind mode would allow players to adjust colors manually or even changes shape/look of some items to allow them to be more easily distinguished.
2. Bubble Info-Having a small icon on the edge of a screen where a player can hover over to get the spell information about the current active bubble would be very helpful.
3. Aura Info-Being able to hover over a player and get the spell info about their active aura would be very helpful as well.
4. Reduce buff clutter-Instead of showing multiple ward, charm, trap, etc buffs of the identical type, why not just use one and the put a small x2, x3, x99 etc over it. This wouldn't eliminate the issue entirely of having a dozen buffs swirling around you and not being able to tell which is which, but it would certainly be a good start.
5. Side Board Display-Hovering over your deck icon while choosing your spell should show a list of the remaining cards in your side board.
6. Scale UI Elements: Allowing a preset increase/decrease of 25% and 50% would make it easier customize and also help with those who need larger displays or who would prefer a smaller display for aesthetic reasons.
Thats just my thoughts but I would like to know if anyone else has any ideas. Keep up the good work KI!
