[HOUSE] Front door, back door system.

Absolutely. I'll add that in a recent SA-MP version, interiors to several San Fierro houses were introduced (these). To make use of those buildings, I think any of those houses above should automatically use those interiors and be in a separate virtual world (where the original house is removed and the SA-MP objects to that house are placed there instead). Several of them have multiple doors and a balcony, and it would be extremely helpful (and look much better) to have interiors that actually match exactly with the exterior.

Edit: Here's what I mean.

Just add doors and windows by default so the player can't escape the interior and it would work.

Definitely. Would save you the trouble of having to PM someone to tell that you're gonna "OOCly" head out of your front door since doing so in the back door isn't possible lol

If things are gonna be like in an open world, I'd say take the windows into consideration as well.

That would also mean that the interior size/details must exactly match its exterior counterpart. Not saying that it's not possible, but it would be a bother to modify most houses in most scenarios, considering how big San Fierro is as a city.
