I like the pdf form template feature. Its currently moderately clunky but benefits mostly outweigh time expended in customising the form template prior to concerting to template. However, its frustrating not being able to view the populated form within Heidi and then, if necessary tweak the output. Ideally I'd like a built in pdf viewer/simple editor so the content of the filled form can be viewed, tweaked if necessary without having to download it and then re-open in a dedicated pdf application. I find despite close attention to the instructions in the Adobe/pdf-filler field instructions Heidi struggles more to accurately follow instructions meaning pdf editing usually needed, but its not practical to 'tweak' the template instructions quickly to test because you have to go back to the original pdf application, make changes, re-upload and test ... life is too short for this
