I looked at splitting the change, but what hit me is that none of the changes I have make much of a difference unless I have background filtering. Unless background filtering is enabled, the UI still remains to be very sluggish. I have attached a screencast with the current version vs the version with my changes. Note, that the UI is sluggish when there are a lot of entries (e.g. 2048) which are also long. This happens quite frequently in my workflow where I copy the contents of whole files - Filip ----------------------------------------------------------- This is an automatically generated e-mail.
