Hi,
1. Check the about dialog, you can find the "BuiltDate is 1/15/2014" , Or you should refresh Ctrl+F5 to reload the editor.
2. You can export the waveform as an Ascii CSV format from the toolbar, BTW, we haven't set a Icon for this function, the tool is nearby the config toolbar.
3. Add access control, so you and your parter can modify the same project. This is not real-time collaboration, so you shouldn't save the same file at the same time, or the last will be the winner. 
4. Ngspice is upgrade to 26.
