Version: 1.2.0 (using Devel) Installed from: Compiled sources OS: Linux Ctrl-mousewheel is a common shortcut for zooming in many apps, e.g. Dolphin and Gwenview. It would be nice if kmplot also followed this convention. Below is a patch to do that. In addition, the patch 1. Removes a variable that is unused due to foreach macro 2. Reworks the animation so that QTimer is used. This avoids spinning the CPU and interfering with the event loop. (Also, MAX is set to 11 now. The old code ran for (MAX+1)*16 ms due to the for loop having a <=. To make the time the same, I set it to 11.) 3. The animation isn't run if KGlobalSettings has them disabled. There is one slight change in the result in that the new graphs are drawn before the animation completes. Is the previous behavior preferred? (I can rework the patch to do that. It made consecutive ctrl-mousewheel zooms (i.e. perform the second zoom before the first's animation completes) kind of weird.)

Very good idea!
