Hi Steve, you're correct that there is no "render history" feature available at this point. It's something we do intend to add in the future. In the meantime Terragen does output renders to a temporary folder, whether aborted or completed, and I find a good approach is just to keep this folder open and use a good image browser like XnView to look at what has been output so far.
In Terragen 2 the output goes to the Temp folder, and you can find the folder(s) with the Explore Temporary Files option the File menu. Temp files are put into a new folder every session (every time you restart the app), and are numbered sequentially (though not consecutively). So just open the most recent folder and you should see all renders done so far in the session in there. They're saved as BMPs in TG2.
In Terragen 3 you have more options. You can choose where the automatic output files go (and whether they are even saved at all), and also what format. New options for 8 or 16 bit compressed TIFF are a good trade-off of file size, flexibility, and compatibility for example.
