cmsrosetta v0.8.1 feedback

[Hachmann]

Listing things I noticed while trying things out:

1) Language overview:
a) The filters shown here at the top don't make sense to me. They don't have any effect if I click on them anyway.
b) The absolute number of entries per language for third-party-apps varies, for example German translators have to translate 3155 entries, and Chinese only 2986. That's because not all po files for all languages have been updated regularly by the third party app's maintainer. For example, mptt only has 22 entries for Chinese, but 28 for French, and cmsrosetta (!) has 4 for Chinese, and 38 for French. No pot files exist for any of them. Is it possible to somehow 'merge' them, without a current pot file?

2) Pages List:
a) Listing pure redirect pages isn't necessary (might already be improved? Didn't test.)
b) Not all pages seem to have the correct menu title (Coding Style would be "Stilkonventionen" and Donate would be "Spenden" in German, while the others are listed with their correct German title)
c) Feature: Could it be possible to display them sorted by menu?

3) Translation page:
a) Feature: When there are only very few items to translate, the button at the bottom only allows to 'Save and quit'. A 'Save and review' button on the last page would be nice, which brings me back to an unfiltered page of the same translation catalog, so I can decide if I want the overview page about all catalogs, or if I would like to check what has been saved (and maybe make some edits).
b) Unfortunately, 'Save and quit' also returns to the language overview, so I have to select my own language again, if I want to continue translating something.
c) I wish there was a warning if I entered a translation, and then choose to go to another page, asking me if I want to save my changes.

4) Pagination:
a) The dots in the pagination section don't need to be in a blue box, that's a bit misleading (I admit I clicked on them, although they were bright blue ;) )
b) The pagination section is a bit too much, for my taste. It shows the previous ten pages, up to page 11, and then the previous 4 and following three plus the last four... Resulting in 18 blue boxes at the bottom. When a filter is on, the ordering will change all the time anyway... so I don't find the pagination so important that it should be so extensive.

5) General:
a) Simultaneous translation by two people is not handled correctly. I think it is intended that a warning is generated if someone else translated the same word at the same time, but what happened for me was that the second person who wanted to save her translations got the message 'No changes to save. So skipped saving anything.' instead, although she had entered a new translation.
b) Is it correct, that if I translate third party apps, such as rosetta itself, this is saved only in the po file in pythonenv/libs/... ?
What will happen when I update rosetta? (I guess the translations will be lost?)
