Revision 1.198: download - view: text, annotated - select for diffs
Fri Nov 28 17:04:25 2008 UTC (15 years, 6 months ago) by bisitz
Branches: MAIN
CVS tags: HEAD

Optimized screen layout for portfolio files in selection mode:
- Wrapped list of selected files from different folders in data table
- Added missing &mt() calls to button texts
- Wrapped buttons in paragraph
- Improved check files message and moved it under the selected files table
  (better place because selection does not take place in the selected files table)
