Each Mega reader takes one shelf of the Jewish library — Tanakh, Mishnah, the Talmud, the siddur, the Mishneh Torah — puts the entire text on a single page, and then piles on everything I wanted while learning it: grammar, sages, commentaries, the day's calendar, and a record of how far I've got.
The whole Hebrew Bible in one reader — every word parsed, every literary device marked.
All six orders in one place, with every Tanna colour-coded so you can see who is arguing with whom.
Every daf in Shas in one reader — and whatever the day's learning produced, pinned to the sugya it belongs to.
The Mishneh Torah, chapter by chapter — seeded with Hilchot Issurei Biah 9, notes pinned to the halachah.
A working siddur that knows what day it is, and a commentary layer that keeps growing.
