I have a trial version of Scrivener 3.0.3 (3032) running alongside Scrivener 126.96.36.199 (26324) on MacOS 10.12.6. In the process of updating a template of mine to Scrivener 3, I saved a test project as the new template with the same name as my old template (because I didn’t realize at the time that Scrivener 2 and 3 were sharing templates). Then I had two templates with the same name that I couldn’t tell apart.
I know that I’m not supposed to be able to use new templates in an old Scrivener (so presumably seeing them there is expected), but I don’t know if I’m supposed to be able to add multiple templates with the same name—in general or in this particular situation. So if this is not a bug report, then it’s a feature request for some way to tell two templates of the same name apart–by the Scrivener version if that’s the only case in which it can happen, or by the date added if it can happen in other cases.
