Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added control views for HUD: The HUD implementation may now be activated by the compile switch ENABLE_HUD_SUPPORT. The HUD will become visible onces detected in the CvOpt overview menu. The first implementation is for testing only => The LEDs may be operated by a number field. Positiv values activate the red, negativ the green LEDs. Depending on the value blink sequences will be scheduled. At the moment no dive specific data is mapped to the LED operation (like e.g. warnings).
