@jbngar the biggest bottleneck is our particular implementation of the display screen. There have been various iterations of it over the years, and they all have had various flaws. Because OpenLP is also a cross-platform app (unlike ProPresenter which wasn't until recently), we have to choose a solution that is going to work across all platforms with minimal effort.<br><br>Of course one of the other factors is that as a group of volunteers working in our spare time we don't have a lot of time to devote to every single feature request. Also, because of this, we can't dedicate a team of experts to develop some uber fast ultra fancy renderer. We'd love to have all the bells and whistles of the commercial apps, but unless we have some fulltime paid developers, there will always be a trade-off.<br>
