[Bletchley Park]

The rotational tool in ligand design is fairly useless in its current implementation. The rotation takes a second to get started, but then races around the clock when the arrow is clicked in either clockwise or counterclockwise direction.

It would have been a better design if this was set up to move in this fashion:

• click on an arrow tool for totation but do not yet move the mouse. The arrow changes color, but no motion takes place as long as you do not move the mouse. (left mouse button remains clicked on)
• move the mouse upward, the rotation is clockwise at the rate of the mouse movement, small movement is small rotation, big movement is big rotation. Make this rotation absolute, so moving the mouse up a little only rotates a little. It does not continue to rotate while the mouse button is pressed.

Same for counterclockwise, click on the arrow and move the mouse down and the thing rotates in the opposite (counterclockwise) direction.

The current implementation is useless.

The ligand rotation tool was designed to work similarly to the Tweak tool for alpha helicies. That is, each "click" rotates the bond by a small amount, and clicking and holding is equivalent to multiple clicks in succession. For fine rotations, it's probably best to do single clicks, rather than click and hold.

That said, the size of the rotations and the frequency of multiple clicks when holding may need some adjustment. Your suggestion is also interesting, and it's also worth considering. Thanks.

The described functionality of "each 'click' rotates the bond by a small amount.." does not work in the windows client. Nothing happens when you click once on either side of the arrow. Where was this functionality documented ? An authorized official user manual would be useful, including an official authorized document on the exact use of all the available programming interfaces.
