Some remarks i would like to be addressed before merging this (i agree with the miss of previous feature)

• 50px for handle is very large. I don't see the requirement for that
• There's a lot of borders added and it's ugly
• i see table tags are involved to do the design, we should avoid this. adding a simple icon to the left of the label should not require a table.
• I would like to have a toggle to move to edit mode, drag controls should not be displayed by default
• there is some right to update savesearches, i guess we should not allow all users by default

Waiting for answers to latest comments.

tested again:

• there's still a larger border than 10.0/bf
  
• new icons should be based on tabler icons library, please don't use anymore font-awesome (lib is present for plugins, we should not use it anymore in core)
• note about the icon choice for drag/drop, you must use grip-vertical for re-ordering vertically

Specific remarks on the toggle as it feels odd with the current design (functionally it's ok)

• icon for [pin] action use a different design and i think more compact (we don't have lot of space here)
• we may move the new action next to [pin]
• the choice of fa-sort is very unusual, i'm not 100% sure how i would have addressed myself the design, but i think i would have explore a more classic [edit mode] design with a classic pencil. But i'm not 100% sure it's not too much . Checking on gmail design, they display the control on desktop only when hovering a row. The feature (moving a mail) doesn't seem to exist in mobile view.

I know i originally suggestion the toggle, but the gmail way seems interesting, to at least, test it and I'm curious to see if it can be better.

good to merge
