I quite agree: simplicity is often the highest form of sophistication, especially when one is trying to avoid "configuration hell." If your current workflow with silversearch is doing the trick, there is no need to clutter the mind with unnecessary extras.
However, should you feel like a touch of improvment without too much headache and you still want to continue to use the Date Picker I might have also an UPDATE to the Date Picker for you too.
New features included:
- Keyboard Navigation: For when reaching for the mouse feels like an unnecessary journey.
- Added Settings Panel: To keep any "tinkering" contained in one tidy corner.
- UI Tweaks: General refinements to keep the interface looking sharp.
It should play quite nicely with your current workflow too, it simply stays entirely out of your way until called upon using the /datepicker slash command.
