So we should have an option to ignore the scroll wheel for rotate/zoom.
Of course for zooming we should have additional keyboard and button
support. And for zooming into a selection rectangle I currently consider
using the middle mouse button. For rotating elements again we will have
keyboard and button support -- but I think using the scroll wheel would
be really fun, i.e for rotating text.

PCB or gschem, one of them, has gesture support by a library -- once I
have asked on this list about it, but it seem that nobody uses that. I
have currently no idea about gestures, so I do not intend supporting it
now.

Yes -- not a true double click (in a small time interval) but simple
adding a net segment of length 0. As supported by gschem. ESC and maybe
another key will also end net segments.

Yes, but grabbing an element in the middle is used generally for moving
or selecting, so we may have a conflict. We may try to resolve it, or
have a "Start new net" button for that case.

I consider a "only onces" mode beside real modal operation: For example,
it may occur that we intend only a single mirror operation without
leaving the current mode (comming back after one mirror operation) or we
want a real mirror mode, where each click on an element will mirror that
one. My current idea: If an element is selected/highlighted then
"mirror" button or key will mirror that selected element. If noting is
selected, then we will enter a permanent mirror mode.

Additional, I will support highlight of elements, when the mouse pointer
is hovering over it. Current highlight method is making colors brighter,
move the element a few pixel to upper right, and draw a shadow,
generating the impression of lifting the elements. Problem: We can not
use white (pin) color, because there is no brighter shade of white, and
shadow works not good for dark backgrounds. Of course we can always use
fallback to a plain monochrome highlight color. Another method is
drawing highlighted elements with thicker lines -- I have not tested
that yet.

Best regards,
