Nice but could be more flexible. Puntuado con 4 de 5 estrellas

stl could be made more flexible. For example:
* let user configure a pattern to compute file name (instead of a check box "choose page title")
* option to save selection as HTML (à la SaveSel).

The thing that make this app different from similar ones is that it directly saves into a file.

Regarding other aspects, other add-ons are better. For example, several other users writing review here actually needed "Easy Copy" or "SaveSel".

I chose "Easy Copy" instead because it allows to combine many use cases that would otherwise need several add-ons (though Easy Copy does not directly save to file).

Depending on your needs you might prefer one or the other.
