Scratchpad - editing a script (disable more items, first running) - all, GM_log truncates at NULL byte

Suggestions (for example):
1) Disable view commands (Run, Inspect, Display) from context menu and toolbar. Disable access keys. (https://github.com/greasemonkey/greasemonkey/issues/1774). First running Scratchpad - not first line.
2) GM_log truncates at NULL byte (https://github.com/greasemonkey/greasemonkey/issues/1061)
