Stepped resizing #74
Description
Currently, resizing, whether it affects amplitude or the duration of blocks, is implemented in a traditional manner, where the new value is calculated based on the current cursor position. While this approach offers flexibility, some users might prefer a stepped resizing mode. In this mode, the cursor movement snaps to predefined intervals (e.g., 0 ms, 20 ms, 40 ms, ...), providing a more controlled and consistent adjustment behavior.
This stepped resizing mode should be accessible via a keyboard shortcut (e.g., Shift + Ctrl) and through a toggle button, similar to grid-snapping functionality.
