Its name is Tasty Menu and is a KMenu replacement (oh,no! another one! yah, another one :P).
It’s aim it’s to be a testbed on usability issues rather than eyecandy.
How it will look like? See on the left.
The layout will have three colums (more width than height, shoul look ok also in lower resolutions).
The column on the left (the more accessible onr) will be for most used applications and for the results of the search field, the second column has the main categories and the column on the right contains the items of each category. It’s still too alpha for being released, but I feel it already more confortable than standard kmenu.
Stay tuned for more details and a first release!
