When drawing a substructure query in the sketcher of the Structure Search page, it is quite possible to be unsure of which bond type is appropriate. In these cases it would be useful to have an easy option to select the 'any' bond type from a drop-down bond type menu in the Elemental sketcher.

  •  Frankly spoken, I have difficulties to imagine how a quick and meaningful (first) substructure search is possible WITHOUT having the "any bond" option. I am an inorganic chemist but the same difficulties persisted when I was searching purely organic compounds. Am I the only one?

  • Ideally "add any bond" should be available on the top tool bar, alongside the add single, double and triple bond options.

    Similar "any metal" should be available as an option on the element chooser. For me this would be more considerably more useful than the other seven options available.
