I just downloaded Semagic to try it out as a new LJ client. I noticed that tags are being used in some journals, so I wanted to see if it would work on this journal client as well, instead of having to manually edit them after posting. I like that this client gives me full font and layout editing, which means I don't have to worry about html codes anymore...
I see you can easily add in references to other LJ users
sstormwatch, communities
dressdiaries (although you have to type in the name of the user or community, instead of a ready drop down box which would be nicer), even lj cuts and cut ends...
I will have to test this one for a few days, ...
We shall see this client is worthy of continued use, but it looks very promising.
