- Start in root folder so that large directories (/bin/, Windows) are easily reachable - Remove the line edit and navigate by double clicking instead since this is more in line with expectations - Use a QPlainTextEdit for logging - Make the log message more informative - Add icons Change-Id: Ia3cd7fc143efef80772923291f0b711913aa47be Reviewed-by: Paul Wicking <paul.wicking@qt.io> (cherry picked from commit 2393a40ccd455cc2dca410e8a1830856dbfde12d)
