I think I may have the fix for that… I think the case you’re referring to is when in piece (detail) mode and you go to drag a piece and it zips way off the screen… correct? Although doesn’t it do a similar thing when you try and drag a point label around in draft mode - like when zoomed way in?
I will though be adding a few new prefs that control the speed of the wheel and the scroll bars.
I’m also adding a pref setting that flips the use of the Ctrl when using the wheel… most graphics programs DO NOT use Ctrl - Wheel to zoom, so for those like me you’ll be able to use the wheel on it’s own without needing the key modifier.
You’ll might find the Zoom to Selected Area via rubberbanding useful.
Oh… and I forgot you’ll be able to Zoom to Fit by double clicking… at least in draft mode. I can probably get the double click to work in piece mode too to “zoom to fit” a piece.
And since it’s pan & zoom related, I may as well add the gesture control for touchscreens. Back when, I mistakenly added it on my fork thinking the Qt gesture stuff controlled a trackpad on a laptop - doh. Since I didn’t have a touch screen at the time I couldn’t test it. Now I can with my new laptop.
