I know Leadwerks loads up pretty fast, but I dream about one day having some sort of splash page which shows it's status as it loads all the elements.
If you add a lot of (steam) workshop items at the same time, THEN go to launch the program it shows that there is a Leadwerks application running in the task tray but the title is blank. Click on it and you see a white square in the middle of your screen. If my hard drive wasn't making all kinds of noise I would think it was broken, but if you look in resource management you can see my hard drive is going over all the leadwerks files. If you add a LOT of workshop items on a slower computer, it can sit on that white square for like 2-3 hours.
So basically whenever it is "loading workshop" (and potentially countless other things?) it should have a nice splash page/box that says that it is working.
