MewBot is acting odd
This happened, the bot seems to be removing the past participle and past singular forms from the nl-verb headword line template (also on other entries)? Not sure if intended, thought you should be aware!
No, that's intended. Since the inflection table already shows these forms even when collapsed, showing them also in the headword line is redundant.
That makes sense -- but then I think there ought to be some kind of parameter to set in the nl-verb template so it doesn't show the [please provide] text in the headword line, now it just ends up looking incomplete.
In case you have Greek terms in your sights - forms are shown in the HWL that appear in Greek dictionaries (eg the feminine & neuter forms of adjectives). In most cases they tell you all you need in order to 'get' the paradigm. When viewed on a computer these forms may be superfluous, but when viewed on a mobile telephone they make it unnecessary to view the whole table which with some terms may exceed screen width. I would request that the HWL are not changed.
