Hi,

I cannot get the + sign to show up using the latest versions of Material Theme and Material syntax.

Here is a video of the issue: https://gfycat.com/HeartyGlaringAplomadofalcon

macOS: Sierra 10.12.2
Atom version: 1.12.9

Atom 1.10.2
one-light-ui 1.5.0
one-dark-ui 1.5.0

• Set UI theme to One Light or One Dark (not sure if any other themes have tab sizing options)
• Set Tab Sizing to Minimum

New tab button plus symbol appears to be partially hidden.

If I have a lot of tabs, they end up going behind the new tab button instead of the new tab button having its own dedicated space. It would be nice if this did not happen.

Also when I mouse over the new tab button, it gets bigger. I don't think it should do that.

This does not play well with the Atom material UI. Everything is fine, but on hover, the + shifts to the right, out of the tab.

Enabling this package causes strange tab reordering issues. Here's an animated gif to show you what I mean:

Originally I filed this against atom/tabs (see atom/tabs#245), but they directed me to package-cop, which helped me narrow down tha it was this package that is causing my problem.

Here's a link to my settings:

I have selected the option to have the new tab option to the right of all open tabs

Even with that selection, after a while the new tab icon comes to the very left of all open tabs

Please fix
