[Have A Miniature Version Of A Creature In A Jar, As A Pet (Synthesis Container)]

Probably Zanuka. He's so cute!

[Which Warframe Is Most Like You?]

Rhino. I'm big and loud and kinda awkward, but people like me anyway.

[Trading/selling Annoyance]

I don't recall the name, but a few years ago I played a game that had a setup that might be viable. Everyone's profile had a spot where you could list 5 items you're looking for, and 5 items you owned and wanted to trade or sell. Made trading as simple as clicking on someone's name. There were still stores and such, but casual trading was a breeze, and if you were patient, you didn't have to do much at all. Eventually someone would come along and offer you what you wanted.

[Which Warframe To Buy? Help Please.]

Weapon and frame slots are a great way to spend platinum. You'll be glad you did later.

[Make The Codex More Useful]

The codex telling you where your clanmates have found certain items is a really good idea. Be a nice "perk" for being in a clan.

[Please Move Ordis! This Really Needs To Be Fixed.]

Same when changing colors. Every third or fourth color you try, he pops up to say one of his "funny" phrases, and blocks the colors you're looking at. Not a huge deal, but kinda annoying. Seems easily fixable.
