I’ve got the same issue. The work-arround I’ve been doing is-
1. Edit the new.xslt file to the new specs
2. Deploy
3. Create new template and name it something.
-Bingo.. new custom template.
Problems: Too many deploys. Have you found a solution to this? I need to be able to edit some CSS. This is a great plugin, I just wish there were more options to have custom element tags.
