I'm here to be educated by you guys.

I could spend a few hours to research myself, but instead I will rely on your expertise. So I noticed a lot of dotted rhythms in Chopin mazurkas.
The typical "mazur" rhythm is
3/4 time: dotted 8th note, 16th note, quarter note, quarter note
So I see this rhythm
throughout the many Chopin mazurkas. I also see this rhythm at the beginning of Schumann's Carnaval op. 9.
Schumann also used dotted rhythms in the finale of his symphonic etudes and in the 2nd movement of his Fantasie op 17 2nd movement. In the case of the Fantasie - he does not use dotted rhythms any more than Beethoven did in his 2nd movement of the op 101 piano sonata. Beethoven also used dotted rhythms throughout his boogie-woogie variation of the sonata no 32 and in other places.
My questions:
1) What other works of Chopin used dotted rhythms besides his many mazurkas?
2) What other works of Schumann used dotted rhythms besides the 3 works I mention?
3) Did Chopin overuse dotted rhythms?
4) Did Schumann overuse dotted rhythms?
Thank you.
