Hey @Pedro_Reyes
I sent a PR with the improvement I mentioned before
Regarding the amount of elements on the left menu, I think that's a big business decision that's out of my hands, since we're actually aiming for those elements to be the stars of the show (they're the main Defender components), so although the elements on the left menu are hidden, I don't think they should be on the left menu.
I'll circle this with the team anyway, so we have a record this was suggested.
If you have any idea of how to make the right menu more visible without conflicting with the left menu, it'd be appreciated as always.
Could we add to the tables checkbox to select and remove more than row at the same time?
Regarding this, I agree with you and that's something I've been thinking about for a while. However, the backend is not prepared for that and it's not that easy of a change, but again, we'll keep note of this and see if it's addressable in the near future 
Thanks for your feedback as always!
