Tried to edit my message above and couldn't. If I insert a screenshot from an attachment into a message, save it, then click edit to write something else under the screenshot, it doesn't work properly. I place the mouse cursor under the screenshot, press Enter to start a new line, but the screenshot moves down along with the cursor.
In the editor, I added handling for the case of clicking the mouse under an image and then pressing Enter, so the image no longer moves down.
The bottom thread with templates became bold while being offline. I logged in, left a comment (the thread above), and logged out, but the thread didn't become read from being offline; after that, I logged in and out. All threads from offline should probably become read.
Upon logout, read status is now reset for guest viewing. After login, the account status is used.
