* 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
