After building Bashed Patch with some plugins there are pluses and dots. Do I have to select the plugins to be a sign with them as with the rest of the plugins? In OBMM these plugins look like they were not activated.

The mods are either merged or imported into the bashed patch, but if you need to know more about the bashed patch I suggest that you post your question http://www.gamesas.com/index.php?/topic/1221023-relz-wrye-bash/.
