Feature request #4307

Updated by Paolo Cavallini about 2 years ago

Methods to save a file are different in different commands and plugins, e.g.:

* sometimes the file extension has to be chosen, sometimes not

* sometimes the file format cannot be chosen (e.g. for interpolation plugin)

* the target directory is not always the same.

We should have an uniform method, and use it consistently.

Similarly for Open file.
