I recently added a new option in the menu of Entropedia where you can select a planet. By doing so, only the items that are found on that planet are shown (given of course that the data entered by users is correct). The Link to the Arkadia version of entropedia is: http://planetarkadia.entropedia.info/ This will only have effect on charts that have a planet column ("Found on"). You can always choose "All" in the planet filter to see all items again. I also made an Arkadia theme for Entropedia. You can select it on the Account page (I am actually using that one myself now, it requires an account though). Suggestions are welcome.
