* Layer data editor window: fix sorting for columns in region model, add Find feature * RDF import: assign names to layers based on event types, if no suitable labels are found in the RDF * Add label to status bar showing the last text that was passed in current layer (so e.g. counting 1, 2, 3, 4 if that's what beats are labelled) * Better layout of text labels for region layers in segmentation mode when they are close together * Give text layer the same method for finding "nearest point" as region and note layers, should improve its editability
