Let's talk gauges. Life and magic are one of the hardest things to set up on a subscreen due to the mess that is the interface for them, and it's only made worse when you want something larger than the standard 8x8 life bar or magic gauge, or something vertical.
So what to do about it? Let's reinvent it for the next RC!
My biggest suggestion is that we get rid of all the magic and hearts being several separate things on the element list and merge them into one flexible element simply called Gauge. From here what the gauge represents is up to the user - It can track health, magic, a number of an item, or a scripted value. The user can also choose how this is visualized - A bar with or without caps and container (basically a 16x16 bar/container midsection stretched out to the defined max length minus cap lengths), a set of repeating tiles with framesets that change on that value (along with adjustable overlaps), and the option to permanently fix the bar or tile repeat length and have a number use the "current/max" layout with the bar or tiles updating as appropriate when increasing or decreasing the current or max value. This also includes max horizontal size, a toggleable "show active" section as a way to make where the current status of a bar is more visible with a special tile or set of tiles, and a preview mode in the interface itself as it can problematic to work with so many options and numbers and not know what it may look like when you hit OK on the Properties interface.
In other words, the current gauge systems should be retired and only managed for compatibility, and a better and more comprehensive gauge system is really needed.
