Since 1.0.0 Beta I have had two major issues that are not going away with subsequent patches.
1. TSViewer is not displaying correctly, if you use [space_0]_ to create lines, they break out side, and non of the structure is there, displayed as a list.
Also with TSViewer after you edit the setting for the block you cant not change them, if you remove it and replace the values go to default and are not changeable.
2. Registration page broken if you have UIID required and on displayed on registration page.
