- Ability to manually mark a quote as invoiced (weird css fix for this, we can remove the custom css if we make the parent button just a dropdown, but don't want to introduce extra clicks)
- When converting a quote to an invoice, show the new invoice number in the quote history
- Quotes can now be sent from the main Send dropdown, instead of having to use the send button in the options menu / main quotes.php page
- Move more things to new permissions system
- Deduplicate assets post logic into model
- Swap out some "SELECT *" queries when only a couple of rows are actually needed
- Split into admin and user handlers, each admin page gets its own file now
- Enforce role access once for admin POST requests
- Automatically load POST logic for admin-based requests based on the referring page, otherwise automatically load all user request logic
- Add support for using custom POST handlers
