Extremely simple toldyouso app. Supports adding items, checking items, editing items (double click) and automatically computing score. Empty items are removed.
Click the systray icon to show and hide. Ctrl+Q to quit (unless on e. g. macos, it adapts to the platform defaults).
Stores items in ~/toldyouso.txt, one item per line. If the line starts with x it
is done/checked, - (or any other prefix) is unchecked.
qmake && make && ./martin-toldyouso to build and run.
