Tedious busywork

Mind numbing drawing and coding. Things that need to be done. Tell me if any of these are important to you. Maybe I don't need to worry about some of them. 

Edit: Apologies, enabled multiple choices. This of course deleted previous respsonses,

More hairstyles and eye shapes.
We're at the point where named NPCs don't look unique. The solution is obvious: make more. However, I feel that this comes with diminishing returns as spritework becomes increasingly hard to distinguish.

More clothing options.
Specifically mundane uninteresting stuff that's missing. Gloves, hairpins, knee socks. Maybe a couple more skirt lengths. Stuff like that.

Color separation.
Separate the irises for heterochromia.
Eyebrows and eyelashes could be colored through code, rather than being black. This might make blonde and light hair more natural looking.

Full clothing support.
There are still a few poses without any clothing. (Diagonal pose that is used for Banshees and the Flesh Wall and the kneeling variant that's used in tube nightmares.)
And then there are some that don't have the bottom half clothed. (Harlequin scene pose, Harbinger scene pose.)
I haven't been too fussed about these as they don't have many use cases.

Optimization.
There's a lot to do. Is it worth the effort when I could be making content instead?
I mean, the game's already running anyway.

Full mouse support.
Some of the GUIs don't have mouse support. Most noticeably the title screen and the Esc menu. I think the fridge as well?
Does anyone even play this with a mouse?

Controller support.
You could just use Steam or some third party app to map the buttons.

Linux version.
I'm fairly certain people run it through Proton already. Is there a demand for this?

Translation support.
A machine pre-translation would be difficult, due to accuracy and wordplay needed in puzzles, as well a text format.
A live trabslation might be a better option, but I really don't want to integrate any API myself as it opens me up for all sorts of liabilities.
I've made a script that would save on screen dialogue messages into a text file, then read it back on key toggle. It is very raw and would need some ironing out.
The idea is for the user to hook the file to translation service (i.e google translate) and toggle between original text and the translation on key press. This is a somewhat technical solutions that I bet the majority of players wouldn't know how to tackle, so I'm not sure how much effort I should put into this if at all.
