Auto scroll option

[Briix]

Hi,

How would you feel about adding some options for controlling when the auto scroll gets triggered?

We're using gridstack to lay out a configurable widget grid and we're experiencing that people have troubled rearranging the widgets in the grid because the widgets are often somewhat big and easily touch the vertical edges of the container. On top of this we have a sticky header that sits over the grid which is somehow keeping the auto scroll from triggering at the top edge.

I did a bit of experimenting of my own and found that in our case it feels a lot more natural to scroll based on the cursor position instead of the dragged/resized item's boundary box. For us a 20px offset from the cursor (plus a bit to account for the sticky header) was the sweet spot, but I could see this change from project to project.

Would you be open to have an option to set the auto scroll trigger to be based on cursor position, and maybe with optional offset parameters?

Would be happy to contribute the code myself but wanted to check first if this was even something you were interested in having in your library

Thanks :)

having an option seems like a bandaid I rather avoid (and maintain effort nightmare). It's very possible cursor based (like we use for drag&drop using enterEvent which is mouse based) rather than drag object boundary is the better approach, but even drag&drop mouse based which fixed some flickering issues and predictability has it's own issues like #3198

if you can post a video and sample demo showing issue that would help make a case, and is required for me to even consider
