After you open a file or create new file, UniView workspace will change so you can work more efficient. This means toolbar and statusbar changing and updating of menu items. If you want to know how exactly will these items change, check it by yourself directly in program...

Regarding toolbar, most deal of it is common for all file types. Besides other buttons are common buttons: Open file, Save and Save as, buttons for Directory browsing and Clipboard operations, Settings and About program dialog.

I mentioned, that there are several base types of files, that UniView is recognizing. They're:
Text files
Image files
Multimedia files
Binary files

You can modify all types excepting multimedia (AVI, MPG, MOV, QT etc). This type also can't be saved. But there is assumption that this function will be implemented in some of future versions of UniView :-)
