Customizable Breathing Exercises

I would like to request a feature that allows users to create and customize their own breathing exercises within the app. This feature would enable users to tailor the exercises according to their individual needs and preferences, providing a more personalized experience. Key functionalities could include: Setting custom durations for each phase of the breathing exercise (inhale, hold, exhale). Adding or removing steps in the breathing cycle. Option to save and name custom exercises for future use.
