Filters
To access filters dialog click on More Filters button on home page.
Show Only Completed? will show only grid you have completed if checked. Otherwise not started and started grid will be shown.
Show Only Recommended? will show only grids recommended by SV.
If you have created a public grid and it's now visible this checkbox needs to be unchecked for your grid to be visible.
At the moment I'm working on a system for grid recommendations.
If you want to share a grid you've created with someone go to My Grids and open play page
for the grid. Use URL to share the grid with someone. Alternatively use Export/Import button on Play page.
Central part of the Filters dialog is list of variants to include or exclude. By default Don't Exclude is set for all variants.
If Must Have is selected on a variant, only grids which have selected variants will be shown. In this case Killer, Arrow and Thermo.
Exclude will exclude grids with unwanted variants from the list.
Checkbox Must Have Any Of Selected? is checked by default.
In this case when this checkbox is checked list of grids will show all grids which have Killer OR Arrow OR Thermo and exclude all grids which have Kropki.
If you uncheck this checkbox only grids which have Killer AND Arrow AND Thermo will be shown and all Kropki grids will be excluded.
