In shark news ... OK Inkscape news ...
I was hitting a few interface issues, nothing major, just a pain. So I stopped and fixed those rather than creating my shark.
No. 1 Mouse Wheel not zooming (scrolls the canvas up and down)
I believe this stems from Inkscape having such a long heritage, when wheeled mice were not that common? (quick bit of Googling shows this as false, but I remember the days).
There are number of ways of zooming and handling the canvas scroll, but all I want is to zoom in and out using the mouse wheel.
The fix is to find the secret setting.
Edit/Preferences/Behaviour/Scrolling/[X] Mouse wheel zooms by default
No. 2 Control Nodes auto snapping when near Nodes
Seems to be a useful setting, just wish it was not on by default.
Click the Snapping
icon in the top right toolbar to disable All snapping
or try toggling the snapping
I only resorted to this when none of the Node type seemed to revert the snap, but now I can undo it with the Smooth icon every time?!
maybe now I can do some shark-ing
