Hi, Here are two patches:
* "Zoom to fit" on double middle click: resolves the Pcbnew side of https://bugs.launchpad.net/kicad/+bug/1480868. Apparently this is an AutoCAD thing, so it may make lots of people more are home in KiCad. * "Centre on cursor" on middle single click. This is something I made up out of thin air, but it allows people who don't like the warp-on-zoom behaviour to be able to quickly recentre the view using only the mouse. Both these actions are already available from the keyboard (Home and F4). I think ideally these would be configurable as well but there's no framework for that right now. The legacy canvas side is rather more complex, so I haven't attempted it here. My mouse's middle click is pretty terrible, so I rarely use it, and so I'm a bad judge of how useful these patches really are. Fell free to comment on/reject either patch. Cheers, John
