Added "Sync camera position between 2D and 3D modes" (found in Preferences -> Interface -> Options), which automatically centers 2D-mode on camera position when you leave Visual Mode, and places camera at cursor position when you toggle from 2D-mode to Visual Mode (unless you have Visual Mode camera thing in your map).
