1. It can be used to show info in one place quickly, it can also be used b theme authors to pre populate a new field somewhere.
2. You could mean 2 different things here, you can limit a GD widget to only certain pages with the show/hide option.
3. Its your theme CSS breaking it, try this to fix it:
.geodir_event_calendar tr, .geodir_event_calendar td {
line-height: 12px;
padding: 2px !important;
}
4. link? (can’t see it)
5. This is a setting, i have turned it off for you, it can be found under GD>Settings>Locations>Advanced>Archive urls on details page
6. There is a setting for how to show the listings view, when you as an admin save a template page then that saved setting is removed so that you can instantly see the setting u just set rather than what you have saved in the past (which might make u think ur change did not take place)
7. Very soon.
