I'll take a look to see what's up with the outfit thing. Ultimately, I want to replace them with different animations. What you see in game is basically a placeholder system that stuck. Dunno when I'll get time to do it, so right now replacing it, and/or fixing the bug relating to the notifications is a fairly low priority. I've put it on the list though. Thanks.
In the next update, the 2nd year students will be showing up. They're mostly background characters meant for the purpose of populating the academy a bit more, but I do plan some scenes with them, as well as some characterisation, just not to the same extent as the main 7. I'm trying to make sure this doesn't become one of those games with 30 different girls, and maybe only a couple of them ever end up getting fleshed out. That said...
There are a couple of other girls who will be joining the story after a while, but I don't expect them to show up in the next update. Most likely the one after that. These girls are technically side girls, but they're side girls who have significance in the stories of some of the main girls, so they'll be joining the story as actual characters, who will most likely get places in the profile screen, even though they won't have as much content or attention as the main 7.
Named saves are something that was asked for a bunch. Mainly because of how much the story branches and/or is planned to branch. However, I do plan to put on a toggle for it in the next update.
Most people who wanted named saves said it was because they didn't want to have to play though the whole game again to unlock everything, so they needed the named saves to keep track of key choices so they could unlock all the scenes. The gallery unlock is a very recent addition. Even though it does unlock all scenes, it doesn't unlock the build up to those scenes. Regardless of their reasons, yeah it was a popular request, so I put it in, I just forgot to make it optional at the time. It's on the list.
With regard to download size restrictions, I'll probably look at getting Gdrive set up as a proper secondary host for the game. I was impressed by how quickly the game uploaded to it. I'll still use mega as my primary since most people seem to have no issue with that, but it can't hurt to have Gdrive as another option. $2/month for 100gb of storage seems fine for me as long as they don't impose some kind of download limit.
