I just finished up a massive project to completely rewrite the mapping software. There are lots of new features, and it should be faster, easier, more stable, and data-efficient. The highlights:

• Filter presets in the header (including some defaults), which can be saved/bookmarked/shared.
• Gyms now have team ownership, badge tracking/display, volatility ratings, and names on the icons if you zoom in.
• Looking for easy drops? You can add filters to only show gyms from your team with open spots.
• Raids can now be independently filtered by level, so you can show only level 3 raids if you have a quest.
• Grunts/Lures/Quests have all been folded into the Stops filter, and you can choose one of those overlays to display.
• The S2 view now shows how many gyms there are in a level 14 cell, and portals have 20m radius circles to help in placement.
• Nests and S2 views are now independent, and can be found in the presets dropdown.
• Hidden markers can now be unhidden from the settings screen.
• To save a preset, set your filters, and click the "Save Preset" link at the bottom of the filters popup.
• To update a preset, change the filters you want, then choose the edit icon next to it in the presets dropdown, and click "Replace Filters".

I'm sure there are lots of bugs, so drop me a line if you have any questions/comments/problems. Much more to come, stay tuned!
