Have they fixed 'Open in Conversation', the position of the New Message button, total number of messages indicator, tabs and toolbar buttons sharing the same row, the settings button, laggy UI, compatibility with various extensions or the search bar, all of which have been either completely broken or borderline unusable since their utterly unnecessary UI mangling in version 115, their self-proclaimed 'most beautiful Thunderbird yet'?

Or have they just added more padding around everything, more wasted screen space, more laggy animations, all the while making routine operations like, oh I don't know, checking and replying to email more unpleasant and niggling by the day?
