Plz fix bug first and add new feature later

Plz fix bug first and add new feature later

I don't know why it takes so long time to fix bugs . 
It looks like that fixing bug is too delayed compared to implement new features 

- Weired table
- Blank space of  collapsed left panel
- default OR operator of multiple tag search
      I think it's a bug. No other notes use tag for OR operator . Tag is for AND operator.
