Just a small item for the column screen: a counter of the number of items, ie, the number of columns in a table.
Now I usually filter on ‘calculation type = expression’ and deduct the resulting rows from the number mentioned under ‘No. of columns’ in the corresponding table, but it seems a waste not to use the aggregation function of the SF for this.
I still need to apply the filter of course to see how many columns the database has, but it saves a few clicks.
