Marcus Hirt has updated the pull request incrementally with one additional commit since the last revision:

  Now method selections are working in the compilation page and the TLAB page (methods tab), support for new method selection mode in views, support in the properties view for such selections, currently supported by the Stacktrace View (not disrupting existing view selections), support for event type filters, support for picking attribute to use for frame width, support for pinning the current method selection
