○ with name week04-group0X-roomY (0X is seminar group, Y is breakout room number)
○ If you from group PV168/01 and breakout room 3, branch name is week04-group01-room3
● Pavel Hrdina or Petr Adámek will give you write access to calculator
repository

○ Petr or Pavel will visit your breakout room to ask who is this person
○ In the meantime work on other tasks
● Push the branch to origin repository
Seminar task

● Modify the application to show 2 independent calculator windows
○ Make sure both windows work correctly
