fasterwp the tide template is based on Tabler, I use this on my site. There are a few bugs that need to be fixed for V0.6.0 however (pull request submitted).
I was going to create a new post requesting the foss billing team, use the tide theme as default going forward and take over its development. As the admin theme is based on Tabler, it would make sense to use Tabler for the client side template too.
