CCL: input structure creation/editing



Dear CCLers,
 
which program running under GNU/Linux would you recommend for the creation and editing of the input structures
for the quantum-chemical calculations? Molden is good for inputs using Z-matrices, but is very inconvenient for the free-hand "fine-tuning" of the guess structures, say for the transition states. Ghemical is not bad but its development seem to be stopped.
Something as simple as the editor built-in in WebMO would be good...
 
Thank you.
 
 
Best regards,
