Sweatbox Builder v7.9.0

• Edit a flight plan without leaving the pool. Every row in FPLN POOL →
  POOL now has a pencil. Press it and the row opens in place: callsign,
  aircraft type, departure, arrival, flight level, squawk and the full route,
  each in its own box. Enter saves, Escape cancels. A callsign that another
  entry already uses is refused on the spot, with the reason shown — two
  entries sharing one would silently merge the next time anything was added.
• Copy a plan into a whole family. The copy button next to the pencil
  makes a copy of the entry under the next free callsign: the last character
  is swapped for a letter, A to Z — AFR1234 becomes AFR123A, then
  AFR123B, and so on. Select several entries and the footer offers
  COPY ×N for up to 25 copies of each in one go. A copy is the entire entry
  — route, squawk, type, level, where it came from — and a pool rule spawns
  one aircraft per entry, so ten spaced inbounds on a route you fetched once
  are a few clicks away. Copies sit right under their original, and copies of
  a selected entry are selected too, ready for ADD TO BOARD.
• Letters already taken in the pool are skipped, so copying twice never makes
  a duplicate, two originals that differ only in their last digit never
  collide, and the family stops when the alphabet runs out. The footer only
  copies the selected rows you can see, and if the callsign filter would hide
  the fresh copies it is cleared and the message says so.
• The row actions (edit · copy · remove) appear when you hover a row, as they
  do on the traffic board.
