Feature request: disable tab drag, and/or drag window into tab

Hi,

I often inadvertently drag tabs off of a window, which can be very annoying (usually happens when i click-and-drag to select text).

Would love to see a feature whereby i could:

• in settings, disable the ability to drag tabs off a window (or ask for confirmation before tab is dropped)
• or, would it be possible to drag a standalone window into another window as a new tab (ie drag it back to the window i dragged it off of)
• or, an "Undo drag off window"

Something like that :)

Thanks for your consideration.

Richard

EDIT: i see similar request in Issue #4782
