A self-update could relaunch Skim into a window with a titlebar and nothing. Restarts didn't help. Reinstalling didn't help. Then, hours later, it just came back which is somehow more unsettling than staying broken.
Turns out nothing was broken. The whole UI was waiting on the first mailbox query, that query was politely queued behind the catch-up sync, and the app had no way to say "hang on, I'm reading" so it said nothing at all. For hours. In an empty window. Cool.
Are you totally against sharing your personal data to companies? or are you neutral and think your info doesn't matter that much? Not just words from dictation apps, but other personal details like schedules from a productivity app, or computer details from coding agents. Asking this cause I personally don't mind my app data being sent to companies, as long as they're not passwords, or important personal info. But this brings us to another question, where is the line?
