Any plans on updating this mod for the experimental version?

A release is planned for the first of July. By then hopefully a fair number of the most popular mods will be updated for 2.1 before then.
Any mod that updates and changes its thumbnail essentially breaks/forces Modlist UI to have the mod-portal-blob be updated again, so the later I wait, the better.

So, another modder informed me that changing the factorio version in info.json from 2.0 to 2.1 allows it to be loaded, and most mods seem to still work just fine with the update as of now (this mod included). I'll come back if I have any issues. Thanks for making the mod!

Edit: Also yeah I can understand why you'd want to wait.
