It looks like a great project, but I can imagine it is hard for the maintainer to have time to add these features without any financial compensation. I'm not in a good financial place to make How to Convert open source yet, so am hoping users paying the current $7.5 will help support it's development.
It's a one time fee that gives you the project forever.
On another note it would be great if you could change how you display those 2077 conversions in your website, I find it really awkward to look at them by scrolling and if my mouse get out of the popup it disappear.
If you can do something "similar" to FileConverter where you can see all of them (at least a lot) on one screen, it helps with doing CTRL + F and searching your file format. :)
GL with the startup man
Wouldn't it be a good idea that you make a normal website to convert file format like any others, but the online service serve as an ad for your offline conversion app ?
Working on improving it at the moment
