Stick with the pricing. The application is niche, and as such should have a higher price. It has been noted many times over that software has a bimodal pricing scheme - very cheap for off the shelf software, and very expensive for bespoke software. But of course, that's the black and white view of the world. The more 'niche' your off-the-shelf software is, the closer it gets to being bespoke, and the price should rise accordingly. It works in the other direction as well of course - if you can build an application by simply tweaking an existing framework, such as building a website using Squarespace, then this should cost much less than true bespoke software.

All of which is to say that I feel that you have the right approach to software pricing. I hadn't realized this exists, but I may well become a customer in the next few days - I have been looking at options for creating UML documents in code.

One thing though, do you have a re-import feature? This is the killer feature for me - I would love to be able to create a URL diagram in your app, paste it into the top of a source file, and then copy it from the source file back into the app for modification later when the code changes. I realize that this is a tricky problem to solve, but solving it takes this from being a toy to being a true industrial tool from my perspective.
