Solid updates, cheers!
Issues:
Upgrades window "resets" constantly (some sort of polling) when scrolled down. If you scroll down in this window, especially in combat, it resets after a second or two. Something to bear in mind when you actually implement rebirth. Actually.. same behaviour on the Options window during combat too.
Slaying can't be disabled - could you mirror mir behaviour and allow disabling? Interferes with pretty much everything (TDB, H.Moon etc)
Nice to haves:
Healing - ability to set custom HP % for when healing should apply, rather than the current roughly half HP, which also triggers HP pot.
Larger dialog window - especially for the trader but applies to most dialog/shop windows. Appreciate you've tried to squeeze it into an existing background image but if you could increase the height by 30-40% it'd still fit nicely on screen and would drastically improve usability of the shops.
