'Stops' in the extension slider
Anecdotally, it seems that some users may end up asking for longer extensions than they intend to because of the way the extension slider works. eg. if they are intending to request an amount of time that will be auto-approved, it's hard to stop the slider at exactly that point, meaning they may ask for a few hours or days that they didn't intend to. We should consider whether we can or should make it easier to ask for the exact amounts of time that hit various thresholds to save users from having to try to fine-tune the slider - this may also lower the burden on us with respect to having fewer small extension requests to process.
