I'm sure this has been questioned before, but: Is there a reason for not being able to remove things like materials from the treasury? It's a shame when people place then in there without knowing that you cannot retrieve them.

Title says it. Vials are there, so why not Barriers?
Also, I would like to see the recon flare, turret kit, and artillary... but mechaknight kits weren't there before and would get messy with people spamming them.

this is my idea for new types of guns

So pierce gun is a gun that can hit multiple monster on a straight line . but it cannot pierce ALL monsters in one hit . just 2 or three foes on a straight line (Maybe)
But if the bullet have been hit the first enemy the dammage will be halved then if the bullet hit the 2nd monster the bullet dammage will halved(Again?)
The bullet can't pierce through walls & unbreakable things
If you charge pierce gun it will pierce more monsters (3~5) with a bit of more dammage

And snipe gun is a gun that have more range than other gun ,

Hello fellow knights!

So you may have noticed the new walking animation in Spiral Knights recently. Well actually the walking animation hasn't even been changed at all. They just further separated our arms from our bodies. If you look closely in-game then you'll be able to spot it unless you never even payed attention to it in the past to begin with. It kind of bothers me a little bit because it doesn't match with my eye type, height, and how I act in the game. The walk now makes me feel as if I'm now an intimidating knight even though I'm not. ._.

In the forums and in the game, we need a way to easily see what the player's previous names were. This is to stop impersonation when, say, Gary changes his name to something else for some reason. Then Mary changes her name to Gary. Mary can ruin Gary's reputation horribly, and original Gary can't do anything to stop her unless he previously told everyone about the name change BEFORE it happened. (Or the GMs dig through the records.)

Please fix/change the following 6 (possibly 7 or 8 depending on Spark of Life update) achievements so that they are achievable and will register with Steam:

MINOR MINER - suggestion - Mine your first mineral.

MODERATE MINER - suggestion - Mine 100 minerals.

MAJOR MINER - suggestion - Mine 500 minerals.

MARVELOUS MINER - suggestion - Mine 1,000 minerals.

MASTER MINER - suggestion - Mine 10,000 minerals.

WALK IT OFF - suggestion - Complete a level with 5% (or less) life.

As stated.

-Assess whether Java is still the best option for the game, and if you can afford to change. (if you've not already)

So apparently, Name Changes have came, but I would like to put an improvement:

Make the knight's old username unavailable for 30 days.

Nuff said.

[EDIT: If you need clarification on this, I'll explain in the comments.]

With the new addition to be able to change your name, some to a lot of people who are long time users change their name slightly or completely and a lot of people will be looking at their friend list going "who the heck is this person?" a lot. So I was thinking maybe like how SK sends out a little mail saying you slot has expired (just an example) you could send out a little mail to all people on there persons friend list that "Knight A has changed his name to Knight B." or something like that. I mean, you can only change your name every 30 days so it shouldn't spam the mails of people.

After playing Spiral Knights for more than a few months, you probably have seen the same puzzle with the switches, and the same loot room. Levels seem to be made of "parts" stitched together to create the overall level. I think it might be cool if players can make "parts" and submit them for players to test and vote on. Top voted "parts" could be reviewed by a game master or someone certified. for quality control, then implanted into the game. I don't know how possible this would be. Maybe you can think of a better system. What I am really aiming for is more variety in levels.
