Scott, Bert,

Thank you both for your verbose help!

Scott: I read in your project file and saw that, sure enough, it allows me to do what I want. I also realized that it actually modified my Squeakland image - and the next time I started Squeak, your project was displayed (and the Navigator and Supplies tabs were missing - although I realize I can toggle them via the world menu). I'm showing my Etoys naivety here, but it'd be nice if, when I start up Squeak again, that the functionality provided by your project was more subtle :)

Bert:

4e. Replace the text shown there:

setGraphicFromTrails self setGraphic: Form3 ===================== with the following (just copy and paste): ===================== setGraphicFromTrails self setGraphic: ((self costume instVarNamed: #turtleTrailsForm) ifNotNilDo: [:f | f trimBordersOfColor: Color transparent]) ===================== Accept using Cmd-s (Alt-s on PC).

FWIW, I'm unable to copy/past into the tile/text field (I'm on Windows). I've attached images of the steps that I take, after manually typing in the code - basically trying to save it - but Alt-s doesn't seem to do it, nor does using the 'Accept' in the menu. So I'm never able to see this tile appear in the Playfield category.
