I'm not going to post anything particular for this wishlist as such, but I will say this:

The developers themselves requested the modding wishlist so it was created for that purpose. We have had wishlist threads for the vanilla game in the past, but they have usually become too unwieldy (like the bug discussion thread was before the creation of the bug shortlist). Good luck in maintaining this list, but you should be aware of what is doable and what is not and consider the impact of suggested changes before blindly adding requests.

I suggest you use the list tags in the bbcode to formulate your list, because otherwise it is going to be unreadable.

As far as using monthly casting, you must have the mage you want selected, then hit shift+m and then select the spell. As long as you have enough gems, it will be cast every month.
