Add an option to postpone breaks from the tray menu

First of all, a massive thank you for the work you do. The app is super cool and it helps a lot of people including me:) I really think it's the best app for taking breaks at the moment 🥳

Is your feature request related to a problem? Please describe.

• Every time I get a notification of an upcoming break when I'm in the middle of something, I feel helpless of just waiting until the break occurs to postpone it from the break screen, when I already now that I need to postpone it.
• I think it would be a good idea to add an option to postpone the break before it actually occurs. For example in the tray menu. In that way you won't be disturbed by a suddenly occuring break and just add some more time to prepare for the break and finish your stuff.

Describe the solution you'd like

• Add a button Postpone for 5 minutes or Add 5 minutes in the tray context menu.
• Or a button Postpone a break with a selection, like For 3 minutes, For 5 minutes or For 10 minutes.

Describe alternatives you've considered

• Right now the breaks can be only postponed from the break screen.
• Similar option is Disable Safe Eyes but I think it serves a different function, e.g. when you really don't need any breaks for a longer time.

Additional context

• Inspired by the feature in long abandoned EyesRelax for Windows, which I still find super useful.
