Feature request: Add Alt + mouse wheel movement like in Litematica

[mllightitup]

Hi! Thanks for making Schematica Plus, it is much more convenient than the original Schematica.

Could you add the Alt + mouse wheel movement from Litematica?

In Litematica, you can select a corner or the whole selection and move it by one block in the direction you are looking:

• selected corner — expands or shrinks the area;
• whole selection — moves the entire area;
• selected schematic — moves the schematic placement.

This is very useful for quickly adjusting selections without opening menus or changing coordinates manually.

It would be great to have the same behavior in Schematica Plus, preferably with a configurable modifier key.

Thanks!
