Speaking of "quality of life" improvements (and feel free to move this post where it needs to be), the quest selection system leaves a lot to be desired and is actually hurting my poor hands.
Instead of having to cycle through each and every quest using a double decline confirmation, I suggest that you adapt the trading post interface to be a quest list. Click on a quest and it opens the interface that lists the available quests (10 per page). Flip through the pages to find the quest you want, and "buy" the quest with the button on the right. This will immediately replace the quest that was in that slot. If the quest needing to be replaced was in progress, put up a confirmation to abandon before the quest list. If the user closes the quest list before selecting one, nothing changes.
This system would save dozens of clicks and time, making me a happy (and more comfortable) camper. One far more willing to financially support an Inno(vative) game that thinks of the welfare of its players.
