Прегледай примерите, които сме дискутирали в темата във форума.

Странно ми е, че си държиш компонентите в UI. Това трябва да е само namespace, който да държи други класове и модули.

Можеш да помислиш върху това да разделиш кода си на повече модули/класове с ясно дефинирани задачи.

В момента ми се струва, че set_text_horizontal, modify_vertical и longest са част от DSL-а, който изпълняваме в блока подаден на TextScreen.draw, а не трябва. Този DSL трябва да е максимално чист и опростен.
