I have created several user scripts to help players be more effective in submitting new candidates for portals, pokéstops or pokégyms.
Displays a 20 meter radius for existing portals, to prevent you from getting 'too close' e-mails. Search and find candidates in the non-highlighted area and you should be good. (excluding OPR location corrections or other candidates coming live before your submit)

Aside from the 20 meter radius, the maximum limit of portals in a L19 cell is 1. This plugin highlights L19 cells which already contain a portal. As with the submitrange plugin. Search and find candidates outside of the highlighted area and you have a better chance of it ever becoming a portal.

Aside from the 20 meter radius, the maximum limit of stops/gyms in a L17 cell is 1. This plugin highlights L17 cells which already contain at least 1 portal (portals are converted to stops and gyms with a max of 1 per L17 cell). As with the submitrange plugin. Search and find candidates outside of the highlighted area and you have a better chance of it ever becoming a stop or gym in Pokémon.

Highlights level 14 cells which are 1 stop short of having an additional gym. By smartly submitting new candidates you can focus on these cells to improve the rate of gyms in your area.
