Here is a related question. I worked on setting up a PTXPrint configuration (fairly complex) in one project. Now I want to start from scratch in a new Paratext project. The configuration for the old project shows up by default when I first open PTXPrint. But if I change the Paratext project selected, all of the details of that first configuration seem to be carried over into the new project… including links to files from the old project, so that when I tell it to do its first Print, it crashes with missing files! (Specifically: the customized settings ptxprint-mods.tex was checked, but that file didn’t exist in this project.) When you select a new Paratext project that has never been selected in PTXPrint, shouldn’t PTXPrint create a default profile for that job? There is some advantage to being able to copy project settings into a new project from an old project, but it seems to me like just starting to work in a new project need to be given a clean slate, so the initial Print can happen without crashing at least! Maybe later on you could select a different project and configuration, then select the target project and give it a new configuration file name. If it sees that you have already done some PTXPrint work in that project, then it would allow the settings to be copied over. (But I don’t know, that’s pretty complex… Maybe you just need a Reset All Settings button, to be able to get a basic default setting that should always work.)
