Hi,
(I think) I found a minor bug (both in v2.10 and v2.11) - when I connect several USB drives using USB HUB, all the usb are connected properly (as sda1, sdb1...), but there is also created one empty directory sda - there probably is a short delay after inserting second USB and before creating the sda directory (on one try I noticed that it was not here at first, but appeared after few seconds) - there also happens some name changing to sdb and back when the USB devices are disconnected and reconnected.
And one more thing (this one I was not able to replicate on neither version, but it happened to me vith v2.11) - somehow (probably because of the "rapid" usb stick switching) the StickMount stopped mounting the USB sticks. When I stopped the APP, deleted its cache and data, it started working again, but then sudenly my tablet rebooted, but I already experienced this kind of behavior (I mean the rebooting) when I disconnect the USB that was being used, so it probably has nothing to do with StickMount (I experienced this on v1.0 (or what was it) on Stock 4.1.2, now I have Stock 4.2.1)
Otherwise, the app is working perfectly. Thank you for your hard work!
