Right now placing gearboxes is unintuitive, because to place a rotated gearbox player has to "craft" vertical gearbox from normal gearbox (and vice-versa).

Please, change the mechanic of placing all the gearbox types to either the same as dispensers use ("front" face of block facing player) or the one log blocks use ("front" in the direction of normal of the clicked block)

The "front" face in case of gearboxes should be the flat side without shaft.

Some gearboxes are rotation-locked to neighboring blocks - for example I can't place a gearshift in different direction than the neighbor gearshift, if placing next to the side with the shaft. Placing them in the reverse order is unlocked though - I can place a gearshift and on it's wooden side put another that has shaft targeted into it.

The wrench can rotate blocks based on which side is being looked at.
