2 years ago thinking this over and some more background from recent discussion:
eg. the if the windpow title of an editor is usually WebxdcName - GroupName and an Webxdc sets its name toEditor - Saved Messages . . . . . . . ., that may trick the user: the real group name won't be shown in many cases as being too far right. instead the user may think one is writing to "Saved Messages".
however, it seems to be a weak attach:
- on all platforms, it is at least currently clear where the Webxdc belongs to as you have to open the chat before. this may change if we would introduce a global gallery or so, but we do not have that (and it is not directly planned)
- the Webxdc does not come from nothing but from the Chat context - so there is not much additional information that can leak
(inb: nstead of truncating, one could replace character sequences in the name that are used as the separator)
however, all in all, i'd say, it still make sense to ensure all information are shown, however, i'd leave that more to the UIs. eg. the UIs can decide much better when to truncate - a too much truncated document title may have issues on its own (imaging one mixes up "Letter to my friend" with "Letter to my enemy" as the title just shows "Letter to my ... - Editor" :)
the name of webxdc is shown in the title bar, together with the chat name; it makes sense to truncate it to some reasonable lenght, sth. as 20 characters.
same for the document name introduced at https://github.com/deltachat/deltachat-core-rust/pull/3317
