Two tabs: AT-RISK (past items likely to be revised) and PREDICTED NEW (brand-new items inferred from the handouts). Each card's back shows why it is at risk or predicted, plus possible revisions or overlaps.
The colour bar below the progress line is draggable โ you can grab the floating dot or any part of the bar. The current segment glows. In Study Mode colours mean your rating; in Exam Mode they mean correct / wrong / untouched.
Filter by source: Past Exam At-Risk Predicted New Exam Traps, or by topic (Motivation, Business, Technology, BPMN, UML, ADL). Chips are hidden in Exam and Delta modes.
The label always shows the current mode. ๐ Mode: In Order follows the source sequence; ๐ Mode: Shuffled randomises. Tapping re-orders instantly without losing your place.
Theme, mode, deck, card index, shuffle state, display order, ratings, exam state, and delta tab are saved in localStorage.
