Why is our application better than open source software?
We solved the problems with our application.
Viewer do not have to see the backstage, all toolboxes should be hidden and should not distract attention from the main screen. To close this gap, we developed two special screens in software, one for the viewer, the other for the scriber. Another significant disadvantage of all drawing apps is the lack of drag and drop elements on the field. Yes, this is possible in Adobe, but this interface is not fit for presentation. We also observed that manually writing fonts on the tablet does not synchronize with the speaker's speech, this happens slowly, which causes the lag and, as a result, the viewer is irritated. Therefore, we created the author's library of manual fonts. In our application all these bugs have been fixed.
