Hi Dave, thanks for posting again here. I have a lot of older email help requests that need a reply, so I’m sorry I missed yours. I’ll follow up in email too, but this is a good place to discuss because other people may be more familiar with Hover than I am.
My first thought is to use Hover to redirect your root domain to a Micro.blog page. There’s a Hover help page here about “forwards” that may help: https://help.hover.com/hc/en-us/articles/217282447-Managing-domain-forwarding
This would probably mean redirecting everyone to your blog subdomain, though. Another way to go would be to actually have 2 blogs on Micro.blog, one for your apps and one for your actual blog. That would give you the most control.
And finally, you could also have everything in one blog on Micro.blog, but have a custom blog home page that showed your apps and also linked to recent blog posts. This could be done with a custom theme that override the home page, as described in this help topic: Custom home page
