Enhance navigation UX

[Tbaut]

• Simple click on a file/folder feels slow
  Our implementation of the double-click makes it so that the simple click feels slow.
  This is directly related to the delay for us to detect a double-click, 250ms. https://github.com/ChainSafe/ui-monorepo/blob/dev/packages/common-theme/src/Hooks/useDoubleClick.ts#L7 Compare this to Dropbox, the click is immediate

• double clicking on a folder selects the name, maybe we should make it un-selectable?
