CVS tags:
HEAD
Portfolio - Improved navigation, layout, and feedback:
- Standard layout and navigation
- Use confirm_success and action_box after an action, e.g. upload a file
- Added explicit action confirmation for each successful action
- Consistent and improved back link after processing an action
- Fitting header level (h3 -> h2)
- Styles
- Filename style for filenames
- Warning style instead of error style for messages with user related errors, e.g. filename not provided and restrict error style for actual errors, e.g. renaming failed
- Improved order of actions
First check and display cleaning of filename / directory name due to invalid characters, then show empty name or file exists error and exit
- Internationalization
- Added missing &mt() call
- Excluded HTML tags from phrase to be translated
- Eliminated double translation
[Work in progress; Works fine and as intended for changed parts]
