[Schabernack]

any intention of merging these changes in? this issue is particularly annoying and reason alone to abandon an otherwise very helpful plugin.

Hi. Any updates?

In the meanwhile I've got https://github.com/lucasicf/vim-smooth-scroll with this commit. I'd like this merged here though.

I fixed #5 in another way. Using original scrolling of vim instead of simulation.
