Hi Yannick,
Count fingerprints are only supported on a subset of fingerprints
(ECFP/Signature IIRC) and you must use binary for the others. Although it's
possible to support it here in theory, there are some pathological SMARTS
queries that take a very long time to count but are quick to match once.
Example would be a pladium/phenyl reagent e.g. Pd(PPh3)3 or something.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
