I got this I believe when it was on Bits du Juor. Could be real nice, but it is lacking in a lot of areas. E.g., scale cannot be set on floor plans. The developer says that setting the page size sets the scale. So if you set the ruler units to be "Feet" and the page size is "Letter", the ruler shows 0.005, 0.010, etc. No way to set 1/4" = 1'0" or anything similar.
Also, if your native language is English you will be either amused or annoyed at several commands and Help pages. They were apparently written in another language and then a translator software used to render it in English. (Maybe Google Translator considering the quality!)
I had written them about the last version which used very ancient Palm devices as mobile devices in all images, but called them "PLAMs". Commands like on the Page Size dialog which has a setting that you can choose called, "Seem to Print Paper". Huh?
As I said, amusing to an extent, but it can get frustrating after a while!
