On 1.0.96, I did run into an issue with tapping on the keyboard suggestion for my username, which would also add a space at the end, so when I tried logging in it would say the login is incorrect even though it worked fine on mobile. This seems to be fixed on the current beta build where Connect will remove any trailing spaces when you tap on login. If you want to switch to the beta branch, there's an option on Connect's Google Play Store page.
The bookmark animation looks a tad faster to me. The options menu animation prompted me to request the option to disable animation effects since I use that fairly often. 😅
That setting should just be for Android system animations. So the animation when switching to or from Connect to another app; for example, these kind of animations would be affected. But animations within the app would need to be adjusted by the app. The dev is pretty receptive to requests and this has garnered a fair amount of support so I think they'll shave off a few hundred milliseconds from the animation to make it look more responsive.
Not sure if intended but the image viewer will close if you pan/drag the image up or down a bit and you don't need to be zoomed in at all. This happens on 1.0.101. From the animation, it looks like the tap to close function leverages this to close the viewer since the image slides up or down to the edge of the screen.
Looks like this issue only occurs with the "Open links in external browser" toggled off in Settings. Until an update comes out, you may want to turn it on since links will work fine with your browser app.
If you toggle "Enable swipe navigation" on in Settings, you can just swipe to the right, when viewing feeds and communities, to access the main menu. In posts, sliping right will bring you back to community view.
Currently, you'll need to toggle the setting by logging into the site you signed up on and going into account settings there. I think Jerboa had a link to your account settings in the app settings so maybe we'll also have that someday, if not direct access.
The animation on the options menu for posts is fine but personally, I prefer speed and forgoing the animation; so an option to disable effect animation would be nice.
Trailing spaces in the username field should be deleted. I was having problems logging in and it took a moment to realize the problem since it was working fine on mobile. On Android, and I think on iOS as well, the keyboards will add a space to end of words by default. I was tapping in the keyboard suggestion for my username and it also added a space afterwards. When I tapped on login, the process included the space, which resulted failure to login. Not sure if having a username property to the field on Connect would help with the Google keyboard in not adding the space.
Settings autosaving was added in the 1.0.96 beta that just came out. You can join the beta by visiting the Play Store page for Connect. Be aware that your settings(includes things like blocked instances and user notes) may be reset and is not transferred over in the beta but I'm not sure if this still an issue in the current beta though.
Unfortunately it's still inaccessible on v1.0.104. Hopefully it's fixed in the next update, which would probably be like in a day or two.
