Someone has compiled a list of 10 great applications, some up and coming, that you may or may not know about and can easily install on Ubuntu 7.04
Follow link for installation instructions and screenshots.
The list of applications from the link:
Soundconverter - Soundconverter is a small application that allow you to convert audio files in many audio types. You can select a lot of options or convert entire folders in just few clicks.
Brasero - Probably one of the best CD/DVD burning application for GNOME.
Full integration with Totem and Beagle.
Jokosher - This is a Garageband-like application with a good list of features (it’s still too young for some users) but with some problems caused principally by the non-existent JACK usage (so there are many alerts).
Sbackup - Absolutely the best solution for Desktop/Power users to backup their data.
Sbackup, a software born during one of the last Google Summer Of Code, allow the user to set all the preferences for a complete or incremental backup.
Here is a quite-complete features list:
* Backup any subset of files and directories
* Exclude files and directories by regex expressions
* Exclude files by type (extension)
* Exclude files by maximum file size
* Backup to local filesystem
* Backup to any Gnome-VFS supported remote filesystem (including sftp and ftp)
* Full and incremental backups
* Scheduling backups via cron
* Gnome GUI for configuration
* Gnome GUI for restore
* Command-line restore tool that also provides a Python API for restoring a file or directory
* Backing up package list in Debian derived distributions
* On restore, existing files are not overwritten, but are renamed to a safe name
Thoggen - This application let you rip DVD into OGG video files.
I think that it’s one of the best software because of its clear and functional interface, understandable from new users too. And, off course, it spreads open formats.
PiTiVi - Ok, ok, this video editing app is still under hard developement but.. I like it!
If someone will help the main developer, probably this will be able to became one of the most requested software by desktop users.
It has a well designed interface, and some intresting ideas.
Disk-Manager - This software automatically detect new Hard drives and/or partitions and allow you to configure their usage in the best way.
It writes changes to /etc/fstab and preserve a sort of “cache” or “history” for every configuration you tried.
It uses Devices IDs instead of UNIX like method (ie. /dev/hda1, /dev/hdc3 etc..).
Tracker - Probably the best solution to index and search your data.
It has a database that can be used trough some APIs to integrate a full and well organized application. For example. Do you need images? Or music? just one click

Authors are currently trying to spread this software inside the GNOME community because it’s faster than beagle (written in MONO) and has a lot of fantastic features (just imagine rhytmbox or f-spot that doesn’t need to watch any directory, leaving all the work to only one app: Tracker).
Affinity - Affinity is one of the much sexy interfaces to programs like tracker and beagle. It could be integrated in the panels like an applet or launched as a normal program in the notification area. Currently in a high level of development, I’m waiting for its future release (0.2) that probably will be one of the best interfaces you’ve ever seen on your Linux installation.
Gnome-compiz-manager - There are almost two ways to configure compiz (desktop effects) on Feisty by default: using the simple interface of the Desktop Effects applet situated in the menu System -> Preferences -> Desktop Effects, or trough the bad (but full of power and highly configurable) interface of gconf (launch gconf-editor with the keyboard shortcut Alt+F2).
Another way is to install this beautiful software that will allow you to configure more option of your compiz installation (including hot-corners, keyboard shortcuts and many more things).
