The aspect of making every theme work is difficult - MKPortal does that, but then again thats a separate script trodding along with SMF.
I think the TinyPortal name is fitting because it will never be a stand-alone , like MKportal or Mambo. It will alwyas be tied with SMF. For now it works with default SMF theme - and my themes(some of them), therefore it might as well be named Blocs Portal or something...(..) I can agreed on that, but the modifications you need to make for other themes to work, is not huge. And its only one file that needs some extra html tables and of course the included TP files.
I think by doing this manually, you can also tailor it a bit to the chosen theme... for instance the left blocls could be under a sidebar - like one theme of AMA where its a sidebar for the menu..the left bar could go under there instead of outside that again. In my Simplicity theme I will make the blocks go under the things on sides already there...
So the name stays - for now.
