Since the migration over I have noticed some issues with tags not behaving the way they did before.
The IMG tag no longer supports resizing of an image down to a thumbnail size by stating its width, which can be worked around through an imagehosting service, but not if hosted personally or on another source.
The CODE tag seems to cause overlapping of the content with that outside the post, and I am sure in the cases of longer samples into the background of subsequent posts by other members.
The code issue can be worked around with quotes, but it does then lose the formatting or having to use a service such as pastebin both of which then really defeats the object.
The image resizing is a stated requirement particularly for UI posting and similar threads, so if someone is able to look into these it would be appreciated.
