The BWS was rebuild so it would be more steam-lined. It was a copy of the PDF until 10.th October.
Component numbers are written in front of the components name, splitted mods are marked by an asterisk and you can jump to the next part of the mod by using the context-menu.
Is there a way to switch between the non-beta view (mods listed as in the pdf) and the new "themes"-organized structure from the current beta? I see the point in dividing a mod's components into sections according as to how they exactly modify the game - but this can make you switch between sections a lot especially when you're cross-checking a single mod with the pdf.
The BWS tells you that there's a conflict and that spell_rev has a conflict with every component of scsII that follows and the author of the BWP would prefer the first one. So if you want every of those SCSII-components, remove spell_rev 0. If you have it the other way around, you probably found a bug that inverted the icons picture. If you can recall anything you did to that spell_rev or can reproduce that behavior, tell me. As a workaround, save your selection and reload it. This way you can "reset" the icons.
The thing is: I didnt even select spell_rev 0. I didnt select any of Spell Revs components and particularly not the core component - I just picked SCS II components.
Seeing as Spell Rev does the same as SCSII does to spells and even more, I can understand why it should be preferred over SCSII. But I didnt like some changes made in the core component, thats why I was confused that BWS moans about conflicts between my SCSII picks and a not selected mod.
Same goes for the fuzz with the conflict with item_rev 0 - didnt select it at all. I checked the Item Revisions readme and it didnt say anything about moving Vecna, Mirror Cloak & Co. to ToB like the SCS II components I selected do. Or maybe I just missed it in the readme.
In the end I just deselected the conflicting components from SCS II and added them back in with the SCSII.exe after BWS was finished with installing. Since SCS is installed more or less at the end of all the mods, I dont think there wasnt a big chance of screwing things up - and according to the WeiDU installer there was only a minor warning with one rather insignificant component.
Havent had a lot of time to check yet, but starting a new game worked fine.
If you think manual installations are faster, try that in the future.
But remember that it's a huge number of components and you'll need to look through those anyway.
Yeah I probably just overreacted since for the last few days I've spent more time checking mod's readmes and trying to get BWS to do what I want it to do, than actually playing the game.
Seeing as BWS really was fast at installing the mods, there's nothing to bitch about. It probably was just a minor bug (either in BWS or in the one sitting in front of the screen).

Having BWP for Baldurs Gate is like the icing on the cake; noone could complain about (free!) cake - unless its a lie...
edit: added my selection ini.
