In the Syllabus tool there should be space (a pixel or two) between "Create syllabus items by number of items needed" and the radio button it describes. Also true of "Create syllabus items by dates" and the radio button it describes.
In the Calendar tool the radio buttons under "Type of calendar to import" are very far apart from the text that describes them.
In Announcements the radio button is properly spaced in relationship to its text: "Only members of this site can see this announcement"
In Resources on the upload screen the padding between the text and the button is correct but there is no delineation between radio button items "Create new version" and "Overwrite existing files" because the padding/margin needs to be larger a the end of the text from the first button to the beginning of the second button. Same with the Search screen.
In Forums there are two different radio button/text paddings within the same tool.
In the Tests and Quizzes settings the padding between the button and the text is different even on the same page. Note the image where the radio buttons look ok but the boxes under them are too tight to the text under "Release questions and the following"
In Dropbox attached is an example of too much space between the buttons and the text.
Chat is too tight (also with regard to the text next to the input boxes)
In Resources ->options you'll see the same padding issue around "Reading List" with the outsized check mark and the box around it so there's no space around the "R".
The email archive spacing is off as well but looked better in 19 because the information text had boxes around it. That page's radio buttons are positioned too far to the left of the frame.
Messages - too wide (then there is no space between "Email address for forwarding:" and the box it describes.)
In Polls the text on the radio buttons is not capitalized so that goes agains convention.
