There are more decent plugins than you can shake a stick at. The problem is that every single one of them slows the loading process down a bit and, furthermore, the plugin menus can get so big you can't find what you want.
It's much better to install only those you really need.
My personal ones are:
Weld
Set Center Point (sic-very useful as an anchor)
Make faces 1.1
Mirror Selection
Dashed Lines
but it all depends on what sort of work you do. All except the Dashed Lines are free, and all, IIRC, are available from the Smustard site.
Dave, thanks for that, I'll take a look. It may well be useful for my illustration work.
Cheers
