I was trying to map EST data & predicted coding sequences on to a genome and was looking for sth. easy to use, with point and click interface that would graphically display BLAT  results and enable me to view the alignments. Once again I could not find any program that would let me do things the way I wanted to do them... so I wrote a little utility that would give me that freedom.
Here is what I came up with. The program has grown quite a bit since the beginning, so it has become less easy/intuitive to use, but MUCH more powerful.
Feature requests are welcome.
