Maybe I'm just the only one, but I tend to clear out multiple notifications with the delete all option, and, when it comes to Mysterious Melody, that means it's easy to miss messages that my MM has sent. Like just now, when they sent me something after bombarding me with gifts and I wasn't able to skim the newest message fast enough to read it all before it was wiped away into the nether x___o I think the message said that they were gonna disappear and be back soon, but I could've easily misread it D:

This would also be helpful for people sending messages as well, just in case they forget if they've already asked if the other person is still around, or if they can't remember if they told their MM that they're going AFK or if they want to tell the person they're going to bed, get distracted, and forget if they told their MM that or not. Or maybe that's just my bad memory speaking...

Maybe like a small sort of chatlog window on the MM page that shows what premade messages you've previously sent and received? Something like

And it can get erased when MM resets, since there's no reason for the previous day's chatlogs to hang around since you've switched present partners.

Or you could just be careful, and make sure you read everything before you just start deleting stuff.

The thing is is I did read the two previously sent messages that my MM gave me before they drowned me in a number of items. Call it bad luck or whatever, but they sent their last gift right as I was deleting everything, which also deleted that one as well, so I wasn't able to read it quick enough to see what it actually said.

I would love a list like this, and if possible, I'd like to even add a sent/received gifts to it, because my memory is super bad and I don't want to gift the same thing several times or accidentally send something back they gave me.

I wouldn't mind this. I don't see what's hard about it, it would be like the forums... Showing the "recent pings" and stuff. I support this, even though it would only need to last 24 hours. Maybe you and your MM have a lot to say. ;p
