I developed QSL because I found myself appreciating existing labeling tools (e.g., VGG Image Annotator, labelImg, VoTT) while also wanting additional features (e.g., remote file labeling, batching, keyboard shortcuts) that didn't all fit neatly into any one of them. Would greatly appreciate feedback from this community, even if it's just to say that I've needlessly re-re-invented the wheel.
