Regarding am/pm vs 24 hour clock, even as someone who is accustomed to the am/pm system, there are many ways in which I prefer 24 hour clock for forums and Tech work, especially when doing time-related comparisons, and even more so when comparing across time zones. Also IMO 24-hour clock is more intuitive for comparisons between GMT 0 vs current local time.
While I'm here, and on another topic: has anyone else noticed recent changes in behavior of text selection and zooming in the app? At some time in the past few weeks some pages seems to have gained the ability to zoom, during which parts of the page remain with their original word wrapping while other parts are not wrapped. Additionally the selection of text within a post being created or edited seems to have gotten easier, in particular long press to select individual word now functions reliably which it did not in the past. This could be due to changes in any of several things in the OS (webview?) but I've seen it on two devices and so was wondering if this has anything to do with the last round of maintenance on the back end.
