Wow. I had no idea. If you open the app directly from the Utilities folder, you can change a bunch of settings without going into Terminal (like where the images are saved and disabling the small thumbnail before the screengrab is saved).
I guess I haven't really needed to find a new macOS Twitter client lately, but upon updating my home computers to High Sierra (finally), I found that the Tweetdeck macOS app doesn't really play nice with it. There's still the Tweetdeck web interface, but that lives in a browser and the way I use my browser on my computers, I can't really have Twitter hidden and buried underneath all my other tabs.
So I went in search of a new alternative. I almost paid for Tweetbot for Mac, and then at the last moment, I discovered Tweeten. Tweeten is based off of Tweetdeck which explains the familiar layout and most of the keyboard shortcuts are the same. There are a few improvements in Tweeten, like layout, account handling, and DM handling, and overall I think it's a solid FREE alternative to the official Twitter app. Tweetdeck users will feel right at home.
OMG. This issue has plagued me for years and I just assumed it was one of Apple's unnerving quirks of programming. But today, the light shines brightly on my productive habits because I finally found out that you can in fact make the default time of a new event in Calendar to be ALL DAY without having to change it after creating an event.
To do this, all you have to do is left-click and drag a small box in the date box in month view. That's it! And if you're creating a multi-day event, just left-click and drag through all the days that the event is scheduled for and the default time will be set to ALL DAY.
