Just a small update today! 

• Fixed issue with curve min/max values resetting when an emitter was selected, which was probably rather annoying!
• Fixed issue where the visibility of an emitter wasn't saved with the project
• Made the emitter name text a bit easier to read in the viewport. Light text on light particles is difficult to see, so there's a bit of a drop shadow now
• Added the ability to lock emitters! Now you don't have to worry about clicking and accidentally moving an emitter that you've put in... just... the right... place. Locked emitters will have a little padlock icon shown next to their name in the emitter list, and also in the viewport
