hide completed tournaments

Hi mate, 

Would it be possible to add:
1) Simple SEO functionality for creation templates for the Tournaments, Games, Players, Leagues. to save a preset scheme for given user roles? I mean functionality to create my own title, description and keywords by using teams names, dates, etc.

For example:
title: team1 - team2: match date: ****

Another option is to add tags (Team name, time, date, player name, score, etc.) to the existing SEO plugins for example Yoast SEO. 
2) Create a script that automatically change game time based on viewers timezone setting.
For example:
If my server is CET time (GMT+2) and event time is 9:00, but user has GMT+1, so the event time should be reduce by 1 (8:00).
3) Replace event time in a widgets, games pages, etc. from time to live if the game is in progress. Will be good to add an option to select a game duration on Tournaments settings.
For example:
If 2 hours is selected for the games duration on Tournaments settings and the game starts at 9:00, it means the time will be replaced by live from 9:00 till 11:00.
4) Add an option to hide completed tournaments from the drop down list.

If someone will have a lot tournaments it will be hard to select the right one, you'll need to spend a lot of time for it. For saving and optimization, will be good to add 2 options:

- add setting on a tournament page to hide it from a drop down list;

- add option set default for Tournament, rounds, etc on the add game page.

Thanks in advance :)
