As a user of JIRA's software,
I would like a lock button (defaults to on) that prevents issues from being re-organised
So that I don't accidentally move issues around when scrolling on a touchscreen device.
Basically, JIRA is nigh on impossible to interact with using a "pocketable" mobile device. (In my case, ZTE T83 with the Firefox web browser.) Not only does the UI need lots of screen real-estate (a problem even on many laptops with 1366×768 pixel screens), but in the backlog, the (small!) elements respond to dragging events almost instantly.
This is exacerbated by having minimal space to stick ones finger that isn't a task entry. The end result being when tapping on tasks or attempting to scroll, the task is often moved to a wildly different position. Add some lag, and you've got a recipe for making a right dog's breakfast of the carefully curated ordering of tasks.
The tasks should be *fixed* in their position, unless the user explicitly tells JIRA that they wish to alter positions, indicated by a padlock icon or similar, at which point the old behaviour should be restored allowing re-arrangement of tasks. The same UI element should also make it possible to re-enable the lock.
