I'd rather not open source it, but I'm definitely open for requests/feedback. In my group we also never use ante's, so your request makes a lot of sense. I'll build an update where the ante is not shown if it is 0, displaying the blinds instead.
I'm also working on an app for Android where players can follow the tournament on their phones, this is now in testing so I'll probably release this change with that update.
Thanks for the input!
