While I travelled through Marocco, I had some kind of inspirative phase. Biber initiated a discussion about changing the controls in the German forum - to make more use of the mouse. Controls is a very basic and important thing that can decide if a newbie gets over the first hour of playing clonk or not. And now we have the possibility to change it.
Here I want to introduce a complete and well-thought-out concept of how the clonks can be controlled more intuitively and effective.

Controlling the clonk
The mouse was since it's introduction just a help to support controlling the clonks. It neither added more control possibilities nor strived to replace the keyboard.
So here is my concept. Till now, the mouse has been used like in Real time strategy games: Giving commands, controlling (half-AI) clonks etc. As a result, it has not been used much because Clonk is just not played like a RTS. This is a completely different use as for example in Soldat or 3D-Shooters where the mouse is used to help to control just one character. So one goal of this concept is now to change this. This is of course a decision against splitscreen players.

W, A, S, D - used for left, right and jump. To make the clonk more agile, where the clonk jumps depends on his speed, additionally you can control his direction of jumping during the jump itself like in any Jump'n'run. The clonk accelerates to a jog if A/D is hold down, however he can run faster if the keys are pressed repeatedly. This is another element from popular Jump'n'runs which would add some fun to controlling the Clonk.
The same controls are used for swimming, climbing, hangling and pushing, of course.

Mouse-Throwing - Now, throwing works with releasing the left mouse button like before but while jumping, too. Additionally, and this is the main idea in using the mouse for this: With the mouse you specify in which direction the Clonk should throw the rock. So, through this, a lot of flexibility is gained, too. Equally, if we use weapons like the crossbow, catapult, cannon or bow, the player specifies the power with which he want to shoot the projectile - the closer the mouse to the clonk the less power is used. Of course, now this only applies to certain weapons like the catapult but could be used for e.g. the bow in the future too. (See attachment 1) While the left button is hold down, a line is shown like a rubber strap which shows the direction and power.

Mouse-Digging - For digging, the mouse is used too: While the right mouse button is hold down, again a rubber strap is shown between the clonk and the mouse and the clonk digs exactly into this direction. This easies the digging a lot. Especially Newbies would often dig themselves a hole where they couldnt' get out anymore. With the mouse, this is much more straightforward. Additionally it adds flexibility and looks better as the tunnels can go into any direction.
While the clonk is grabbing something, inside a building or using a weapon, the mouse-functionality could be used for alternative fire.

S - S is used now for some more things than before to unify the controls: As before S in front of buildings to build, S in front of vehicles to grab/ungrab them, S+Leftclick to put down and additionally S while digging to produce earth chunks and S to chop trees.

A short excursion on Inventory - Why may some clonks have more than one inventory? Because of weapons (old Hazard, Knights), it's ammo and gear as much as tools (Far worlds). Another possibility would have been to create a new clonk for every different functionality like it has been done to some degree especially recently by the creation of kings, magi, sorcerer, trapper, bandit etc.. This is not so far off as for example the standard clonk has already some tools "built in" like a hammer, an axe and a shovel. Inventory and gear is still the better idea than hardcoded specialised clonks, this principle could even advanced to shovels, axes and other tools as usable equipment.
Now, the controls for inventory:

The inventory is switched through with the mousewheel (as before).

CAPS-LOCK - ...is at the right position for being the replacement for double-dig: Use. To use [Space] might suggest itself but I think some players want to assign space for jump instead of W. The same key would be of course used for vehicles and buildings.

Buildings
The last thing that has been bothering me for too long is the controls inside a building. On the lower right corner, one can see a lot of descriptions what the single keys are for which imo only add to the confusion. So, what do you want to do in a building? Basically Get/Store and Sell/buy. Since this is the one big thing you want to do in a building, it earns more than a little context menu space at the border of the screen. Have a look at the attachment 2 and 3, they should be self-explicatory. I suggest a CreateReallyBigMenu and something like a CreateExchange menu which can handle sell/buy, get/store, traders in adventures, lorries etc etc.
