I know this isn't some ground breaking idea or anything but just a good to have feature request to enable the horizontal scrolling throughout the MX Desktop Modeler.
When it comes to working in the Desktop Modeler in a Mac or a Windows Laptop, the track pad horizontal scrolling isn't supported which is a small hiccup with the User experience.
Again although it's not a big thing or not many people's concern among other important things but would appreciate if you can take time to upvote this feature. Cheers! :)
