[Feature]: Sticky Note

Problem/Use Case

Some people might like to keep a message for themself to remember and some might like to keep one to be mindful.

Proposed Solution

There can be a sticky note on top of the timer or on any other suitable place where users can write some stuff (through settings and directly like the todos) in a limited number of words. This should be able to be turned on/off in the settings. It should have its own section in the settings.
