Two ideas:
- “Pull out” button while sexing Jun. Just for convenience; upon clicking the button it changes the sex mode to “manual”, and removes your dick from her. Specially useful if changing positions; pulling out manually has some awkward control on windowed mode.
- Clothing categories when buying or equipping stuff. Search is useful, but sometimes it’s a mess to find what you want, and it’s useful to be able to see (for example) all stockings + stocks together and nothing else.
