Very capable and accessible
This is a very nice editor indeed. If you already know and love vi or emacs, this probably won'nt interest you much.
However, if you are looking for a more learnable text editor that excels at handling very large files (unlike most graphical editors), this will work nicely.
Fantastic database mapping tool!
Produces very attractive graphical representations of your database schema. Works well with postgres 8, and is generally quite impressive. Give it a try.
