-                      v8
+                      v9
    * instead have made it possible to 'measure' the point under the cursor via keypress
  * it would be helpful to display the source name as well, either as a live readback, or as an annotation on the display window (perhaps at the scan boundaries)
    * not implemented in version 1
+   * not implemented in version 1.3
 We want to use this to select subsets of the displayed data and apply flagging commands to the subset.
 …
    * however one does want to be able to flag an entire row while still zoomed in (ie data extends beyond display borders)
      * version 1 can extend the selection to the entire row/column, but only on viewed region
      * it is a simple matter to add this function
+     * version 1.3 can extend the selection to entire row/column, past the viewed region, allowing flagging of all data while zoomed
  * should be able to abort a flagging session, ie throw all flags for the current baseline and/or all baselines flagged so far.
    * version 1 can abort completely, not start again without reloading
    * small amount of effort required for implementation
+   * version 1.3 can discard flags on displayed baseline or all baselines without restarting
  * probably want to use temporary flagging files that only replace the flag file for the dataset at the end of the task
    * version 1 uses in-memory flagging, and applies only at the end
