Hi sst,
1. The "Auto setup templates", "Icons", "Icons set" and "Language files" sections are empty in the package manager if opened in DFR 1.2 because DFR 1.2 already comes with all available auto setup templates, icons and icon sets and of course there are also no language files released since the release (of the not yet released) version 1.2.
2. I will gray out the "Ok" button if there is no text inserted in the URL and the local file input line in the "Add repository" dialog.
3. "Try1URL" is no URL; it's not starting with "http://" or "https://" so DFR fixes this user input error and interprets "Try1URL" as a local file.
4. If you copy the FILE_ID.DIZ to the profiles data folder you can directly open it from the data folder viewer. In post 1.2 builds I will add an "Open file in program files folder" working the same way as the "Open file in data folder" but only listing files that usually contain text or image data (and of course are located in the games program folder). [BTW: Fixed a bug in 1.2b2: When opening a file via "Open file from data folder" the settings which editor or image viewer should be used where ignored. When opening the same file via the data viewer panel at the bottom of the program window everything was right.]
