In many other applications, you are able to close tabs by clicking them with the mouse wheel and this might also be a good idea for filters in Sense.
Having several filters set, the icons on top shrink and you have to aim for the little "x" to remove one or the other. Just clicking them using the wheel is familiar to most people and should ease users live and "integrated experience"...
Thank you for your feedback on ways to improve our product. While this is something we understand would be useful, it's not on the short-term roadmap. Please continue to show your support for this idea.
NOTE: Upon clicking this link 2 tabs may open - please feel free to close the one with a login page. If you only see 1 tab with the login page, please try clicking this link first: Authenticate me! then try the link above again. Ensure pop-up blocker is off.
