Thanks for the feedback! Most of these are already in place -- you can add horizontal rules, and global shortcuts can be configured in the app's settings. I'll look into a the dark theme issue though.
I originally posted last week as a paid product to get some feedback on the idea, but after some thinking decided opening it up as a free resource.
This collection is basically an expanded version of a bookmarks folder I have been collecting for around a decade of building side projects and businesses. I tried breaking it down into an easy to follow format (although I think the navigation is still a little wonky) so that it can be something you refer back – a personal knowledge-base of sorts.
These are just links. Nothing is downloadable, and I don't claim ownership of any of the content in the list.
I realize charging people for this seems a little unorthodox -- it's one of the reasons I posted this on HN before anything, to see what people think of it. Calling it a bookmark folder is a little underselling it; I've spent the better part of a decade collecting most of these links. When I built this, it felt like what I'm offering is the time and effort saved collecting this, instead of the actual content.
