- up to 8 groups
- it should not be possible to "Zatwierdź grupę" after doing that once and going back by using back navigation
- it should not be possible to add team with the same name to a different group. Team name should be unique along all groups
- cannot add two groups with the same name (!) empty doesn't break uniqueness since it's empty
- commonize layout and logo for all pages?
- check for uniqueness - cannot create another toruney with the same name?
- prettify Submit button handler, need to prevent default, so that question mark is not added to URL
- border around forms
- extract style
- agree on sensible theme
- check that each page is rendering (in test)
- fix display name
- handle case when we go back to create toruney app by back button (block after first creation?)
- display tourney name after toruney creation
- on "Dodaj drużynę" - try to make icon with circle and transparent button maybe?
- extract team as an separate object
- work out why I need inline style in Group (margin) and why bootstrap doesn't make the space by default
- add validation states to user inputs
- save state change in cookies and re-open (?)
