@reb-dev I think this is ready for review, but I'm having troubles finding time to update the docs to tell about these new features. If you think that either you or @lee00678 can do it, I would really appreciate it.

[reb-dev]

@rokotyan Nice feature! I will add the docs within the next couple days.

@rokotyan When testing I noticed inconsistent behavior with crosshair when followCursor is false. The place where tooltip is hoverable seems to be random, and it sometimes follows the cursor even when crosshair isn't active.

It is difficult to showcase with a recording but here is an example of what I mean:

I'm wondering if we can rework the logic so crosshair's tooltip can support this feature, or if we should automatically disable it?

[rokotyan]

@reb-dev You're right, I haven't tested this use case, thanks for your attention to detail! I think Crosshair doesn't need a hoverable tooltip, so we can safely disable it. I'll update the PR.

@reb-dev Updated the code

I made some changes to the Tooltip doc page and added the new info in the recent commit.

@lee00678 can you review? Approval needs to be from someone besides the last pusher.

[lee00678]

@reb-dev looks good. Tested the dev examples and docs, both working as expected.

[rokotyan]

Adding support for custom class names which is needed when using createPortal with multiple tooltips. Planning to finish this today.

@reb-dev @lee00678 Pushed a few more commits. Ready for review again.
