Hocuri	60e9a9101a	Don't always show the sender in notifications (#3441 ), Always show "~" before overridden sender names (#3442 ) * Don't always show the sender in notifications In 1:1 chats, don't prepend the sender name to every line. The exception is when the display name is not equal to the chat name (i.e. there is an OverwriteSenderDisplayname), in this case we still prepend it. * Always show the "~" before the sender name if it's overridden When we introduced this, I assume that we weren't sure whether we should do it and only showed it in some places. But I think it's nicer to show the same sender name everywhere, i.e. always add the "~".	2024-11-25 14:44:31 +01:00

Hocuri	a51013cc00	fix: Show composite emojis enlarged, too (#3427 ) fix: Show composite emojis enlarged, too There are a lot of composite emojis like the flags and the family emojis. Here, the grapheme starts with an emoji, but then come some other characters that modify the first emoji (e.g. all flags start with the flag emoji). This PR shows those as big, too, by checking whether a grapheme _starts_ with an emoji to determine whether it's an emoji. --------- Co-authored-by: adb <adb@merlinux.eu>	2024-11-20 13:59:50 +01:00

Hocuri	cc419a9f62	perf: Return early in getTextScale() if text is empty or starts with letter (#3426 ) Not sure why, but `setText()` seems to be called with an empty string very often - for this case it's nice if getTextScale() returns early. If the text starts with a letter, we can also return early.	2024-11-13 20:08:31 +01:00
