We would like to not have the search bar cleared on gui close and not close the gui on jumping to a station. It feels like something there should be a setting for.
I can just add this myself and send you a pull request, but I dont want to do the work if you will not accept it.
With factorio 1.1.8 this basically got implemented into the base game. I will achieve this mod, as soon as 1.1 is stable. Further development is not done. Report bugs and feature requests in the official forum :)
We still use your mod as it is nicer to use, especially as the vanilla version of the train station search has the same issues we were changing in your mod.
If you will archive this mod I will open a feature request there, as you suggested.
