Hi Evren,
> In the future, some tool which removes unnecessary lines would be helpful for such occations, don't you think?
There is some of that function currently in boolean union, when doing a union edges between 2 planes or between 2 pieces that are trimmed portions that share the same full "underlying surface" will be removed.
But edges just by themselves can't really be removed - in order to remove an edge that's on a trim boundary between 2 surfaces those 2 surfaces have to be merged together into one single surface. This can be difficult to do in cases where the control point grids UV directions do not align with one another.

There are a couple of different ways you can fix your example file here - one way is to select the fragmented pieces making up one side and delete them, leaving a hole. Then select the main shape and run Construct > Planar to fill in that planar hole with a capping plane. Repeat on the other side and you'll have your fixed shape.
Another way to tune up your box there is to use Edit > Separate to break it into individual surfaces, then run Boolean Union on the pieces, you'll then get a box with those in between edges removed.
In the future I do also want to extend the Merge command to be able to merge selected faces together. Like I mentioned before though it involves a fusing together of surfaces, not just removal of an edge and it's a bit tricky to make it work well.

Really the main thing to do is not to construct an object like you've got there in the first place. If you have a planar hole to fill in, use Construct > Planar to build a big trimmed plane for it rather than building a bunch of little fragmented pieces...

Evren -
Have you tried Martin's MoI Thread Script? It works well.

Michael,

I wasn't aware of that boolean union's feature. Nice one. Thank you!!

Yes, merge faces would be an awesome addition.
ed,
Yes I'm aware of Martin's script as well. It's a useful script but I think it does not do internal threads and you can't simply boolean difference an external thread because internal threads are a little bit different structure like this:
