Bloated frontend, terrible code

I came across this plugin while evaluating and from the outside this plugin looks great. Solid feature set, good price for the pro bundle, and seemed like this forum had good reviews with support active.
I was about to pull the trigger and purchase the pro bundle but thought i’d look “under the hood” a little deeper before I did, and wow am I glad I did.
There is absolutely ZERO reason in this day and age to load this much code, JS and CSS.
On the calendar view with only 1 event listed, my website went from loading 892kb to over 5 MEGABYTES.
There does not seem to be any kind of modern, solid, frontend code strategy, or even something as simple as….
If X isn’t loaded (or not needed) – don’t load d,e,f,g,h resources.
It seems as though this plugin is loading all the Admin Scripts and Styles on the frontend but I would need to dig in more.
No reason to put localizations into javascript, and force load that file.
No reason to load Editor styles and scripts, absolutely no reason.

This plugin has great potential if they get their frontend out of the garbage.
