Hi
As far as I know there is still no utility provided by c1 to reload components into the toolbox (if there is anyone from C1 reading this and who is in a position to rectify this omission then it would be most welcome). However you can make the process of adding said items back into your toolbox relatively painless.
Once you have selected the Choose Items option to add tools to the toolbox (and waited the usual eternity for it to load (MS keep saying it’s got faster but I’ve yet to be convinced) Make the dialog as large as you can by resizing it. Now add 'C1′ to the filter box which will at least filter out most of what you don’t want. Finally move to the last column header that displays by default (Directory) and click on it to sort all the items by directory. You should now find that all the items that you want to add to your toolbox are neatly sorted into the groups you are most likely to want and adding them to your toolbox should be a simple matter of checking a contiguous set of checkboxes in the row index column and then pressing OK.
Probably not quite as quick as a custom written utility but by far the quickest 'manual’ way to do it.
