Need more user-friendly categories and tags admin

I'm managing a website for an organization with many categories and tags. I've always hated squarespace's way of selecting categories and tags, but I use squarespace everyday so I put up with it. However, others in my organization are going to start accessing the blog to recategorize and retag over 300 posts and their job is going to be much more tedious because of the horrible user experience compared to WordPress (which they are familiar with).

 For tags, you have to type in the first few letters instead of just being able to look at a list and click previously used tags. If you add multiple tags, it becomes difficult to scroll through and see what you've added because the text is so tiny. The text is also tiny with categories, making it difficult to add and select, especially when the list gets big.

Squarespace - please fix this! It shouldn't be a pain to add categories and tags to a post. It should be a seamless, easy process.

@michaeleparkour‘s Chrome extension has UI enhancements that make category and tag maintenance easier.

Extension has all things in one box, but if you really need particular UI Tweaks (you need Tags and Categories editing looks better) - you @mpalmer may look at  https://www.squarewebsites.org/products/squarespace-admin-ui-tweaks only
