QoL additions - Primarily texture list being confusing

[mackandelius]

• First time creation of the actual atlas texture isn't very clear, as you need to know that you have to click the "recreate atlas" button.
• The atlaser works so seamlessly that it might confuse a user into thinking it hasn't done anything.

But the primary thing

• The texture list is confusing to use when you need the textures in a specific order, visual texture slots in the same pattern as the atlas would make this way easier to understand.

not sure how I would directly solve point 2 tbh, other than a annoyance popup telling you its regenerated, but then it would counter the point of how automated it is....
