Higher limits for custom code and Custom HTML (or several named snippets)
Problem
The head and footer custom code fields are each capped at 5,000 characters, and so is the Custom HTML block. A real site quickly needs several snippets in the head: analytics, a consent tool, affiliate network verification, CSS fixes, structured data. We're at 4,997 of 5,000 in the head and 4,913 in the footer, and have had to split Custom HTML content across many blocks to stay under the limit.
Proposal
Either raise the limits (e.g. to 50,000 characters), or let us add several named snippets for head and footer, each with its own on/off switch. Named snippets would also make it clear what each piece of code is for when several people edit the site.
Workaround today
Moving code into an external JS file we host elsewhere, and minifying everything by hand.
