User Interface consistency

[Sebastian-Jung]

[Tested in dev] There are some inconsistencies in the way the user interface is designed:

• Nucleotide selection:
  • In 3D View one can select a nucleotide/cross-over which is then highlighted, but not highlighted in the 2D View (except when clicking on bonds between nucleotides)
  • In 2D View one can select a single nucleotide and it is highlighted in 3D View but not in 2D View -> Request: Make nucleotides highlighted/selectable in 2D View
• Nucleotide focusing on other view:
  • I double right click on a nucleotide/cross-over in 2D View -> I center nudleotide/cross-over in 3D view
  • If trying the same on a nucleotide in 3D View, 2D View doesn't change
  • One can only jump from 3D View to 2D View if double left clicked -> Request: Make centering in different view consistent (Same mouse button/key) and allow nucleotide and cross-over centering for both views
• Nucleotide highlight (Bug?):
  • Moving the mouse in the 2D view over some nucleotides highlights them in the 3D View in green
  • Moving the mouse in 3D view doesn't show any hints in the 2D View (Might be a bug since it was presented in the YouTube Video)

I think in general it might be good to have a way to highlight/select/focus single nucleotides in the 2D View, this would the allow to have a symmetric behavior from 2D and 3D view.

We should indeed highlight selected/hovered nucleotides in the 2D view. Regarding the right click left click inconsistencies we should indeed think of a more intuitive mapping from mouse event to actions

I've started working on a new interface for the 2D view. It is available on the branch remap_clicks. The difference between this new interface and the current one is that the behavior of mouse buttons are changed.

• Left Clicking on a nucleotide selects it, clicking again selects the strands on which the nucleotide lies
• Right Clicking on a nucleotide cuts the strands at that position, or merge it with the neighboring strand (this was the previous behavior of Left Clicking on a nucleotide)
• Double Left clicking on a nucleotide center the nucleotide in the 3D view (previously this was done by double right clicking)

This probably won't be in the next release because I think these kind of changes need some time to mature a bit, and we want to release soon because of #15

I have pushed the new interface to dev. We will include it in the next release
