Players may want more dynamic tokens than the small set provided in MapTool "out-of-the-box."
Load "Devin Night's Tokens," a huge Creative Commons library of cool tokens for GMs and players alike, from MapTool.
Select File > Add Resource to Library...
Select the RPTool's "cog icon" then choose "Devin Night's Tokens"
The 82MB library of tokens may take a while to download, but it is worth it.
MapTool preview of tokens leaves a lot to be desired. Below are several PDFs of contact sheets for the more player-focused token sets. While not numbered, the token on the contact sheet can be matched to the token in the library by counting left-to-right, top-to-bottom, starting at "1".
