Hi, I think it is a good idea to make range sliders in the sidebar jump only by the actual values in the data.
This is particularly useful for date filters, especially because when date fields are showing weekly or monthly data, the period the range slider is showing can be misleading.
For example, for tab showing weekly sales data, when the user moves range slider for the date field from 9th May till 15th May, it would indicate the sales have not changed throughout the period, whereas if the slider jumped from 9th May till 16th May, the user would know there were no entries in between and the charts will all update.
