1. Hot keys for "use healing salve on self" and "use healing salve on other". Obviously the former doesnt require anything more than one key stroke to heal yourself and the latter will make healing salve targeting behave as it currently does (requiring a target).
2. Add a "last hostile target" hotkey option as well as a "last friendly target" hotkey. You would still have to choose the initial target but after that you could just use your hotkeys.
3. Add a section for damage in the status window. For example, if i have a shamshir of frost equipped show the minimum and maximum damage that would be dealt (breaking it down into both nonmagic and magic damage and the bonus cold damage dealt after would be nice as well).
4. The Poison Resist skill should be more useful. As it currently stands it sorta blows goats. It should decrease the intensity as well as the duration (by a random amount of course) to make it more useful. To waste 200 points on a skill that just increases your chance is probably not worth it. (Unless of course you make the resist chance 90% at 200 skill, but then its just broken.)
5. Fix stealing to choose from an array of different item types. This prevents people from carrying one of each different type of virtually worthless items (e.g. corn, apples, pears, wristwatch, etc.) and almost completely negating your stealing because of the wide variety of trash in their backpack.
6. Make potion chugging hotkeys use the corresponding potion in your back of the highest intensity first. If i have a healing potion with an intensity of 3 and another one with an intensity of 1 the hotkey should use the higher first. Chugging should also display a message when you drink, perhaps add a section in the status window for "current effects" or something similar. Oh yeah... and dont let us chug a heal potion when we're not damaged (unless you remove the timer that prevents from rechugging) and dont let us chug a cure when not poisoned. It's just silly!
More suggestions to come :)
