[Feature Request]: Hold down the Shift key to lock the direction in which the node is moving

### What would your feature do ?

Hello, I am now really fond of the new frontend; it keeps bringing me surprises, and almost every time there's an update, I check out the exciting new features right away.
Sometimes in ComfyUI, I line up the nodes neatly, but if I drag a node around, the alignment gets immediately disrupted.
Could it be possible to implement a feature similar to Photoshop where holding down the Shift key locks the direction of node movement?
I know that currently, holding down the Shift key is used for moving multiple nodes, but these functions don't conflict. When moving multiple nodes, releasing the Shift key still allows for free movement of those nodes. The direction-locking would only activate when the Shift key is held down.

### Proposed workflow

no
