annotate audioio/AudioCoreAudioTarget.h @ 187:5a40619c72d8 sv-v1.7.1
* 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
