 Référence : mémoire "gametime-ux-conception" section 2. Repos affiché comme "Repos après cette série", attaché à la série/l'exercice précédent pour suivre le réordonnancement (poignée de déplacement). Pas de repos après la toute dernière série du programme. Ligne résumé attendue sur chaque carte exercice : "X séries · [mesures actives] · Repos Ys".

 Ajout d'exercices depuis la bibliothèque (recherche, badges de mesures). Cartes réordonnables par exercice. Configuration par exercice : nombre de séries, mesures à suivre (sous-ensemble de celles autorisées par l'exercice), cible par mesure activée, repos après chaque série (hérite du défaut programme, surchargeable). Gestion du cas "exercice archivé/supprimé de la bibliothèque". Cf. mémoire "gametime-ux-conception" section 2.
