I tried to create a new workshop dance using the find sequence grid. 
It would be very nice if you could change something:

1.
Please expand the problem checkbox that i can select my user defined options Please make it Tristate:
 a) select only sequences that are marked with that property
 b) select only sequences that are NOT marked with that property 
 c) ignore this property
in example in the actual version you cannot find all sequences with "MAGIC" 
in it because I Have a user property "nice getout" and csds ignore these sequences 
are find only these sequences

2.
Please allow to select many seqeunces and add all these selected sequences 
to a dance or move all selected sequnces to another database the feature remove items 
from grid can remove more than one sequence from the grid in one step
