I still keep googling every once in a while to see if anyone makes a new map of Theros because if/when I run a game there I'd love to have one that just makes me excited to use. Even if it keeps the kind of inane distances that the book's map has, if it at least looks cool I'd feel better about it. Granted, at the end of the day if I want to run a game there I'll go ahead and run it regardless of the map I have (because the game isn't about the map, it's about the stories the players create).
Thus far the only one I've found that has made me go "okay, that's cool"... is this Hexographer map that someone did that I found via a google image search that uses a lot of the different icons to make it more colorful (while still maintaining understanding of location) as well as adding in new named areas to fill in all the spots that were basically open land with no definition in the original map. The only disheartening thing about the map is that when saved as a .png file, the lettering of all the locations is pixelated to the point that much of it is illegible.
If I owned Worldographer I might've gone in and copy overlaid this map in order to create a fascimile of it for myself and used clearer fonts (and which would allow me to have layers to turn the names/tags on and off)... but for now if this is the best I have available for myself, then it's a start.
