Since unlike Factorissimo, this mod requires you to actively press a button (F) to enter the building, instead of just walking into it, it's probably no longer needed to allocate one of the four sides just for entrance like Factorissimo is doing, right?

Can the factory building be (or have a config option to be) designed in a way such that we can enter the factory building from any side by pressing F, and have item/fluid/signal input/output from all four sides?

That will make the factory building so much more useful+make my OCD(-like-feeling) so much better.

Love your mod a lot, I actually tried to make zh-CN and zh-TW locale translations for this mod(see GitHub), keep up the good work!

Edit: Just realized that pressing F to enter works by having invisible items next to the entrance... If that's the case, can the item be re-positioned in any place that's not already occupied by a relay so you can enter from all those places, and even if all of the sides are fully occupied by relays, at least you can still enter from the corner?

It's technically possible to do that, but I don't have graphics that would support it. Unfortunately the person I commissioned the building from is unavailable now.

I intend to have multiple factory types in a future version (and the code already supports different sizes and inputs on the bottom), but without graphics and time I can't add it :P
