I want to add a defualt value for the built-in site column named Title. now i went to "site collection>>site settings>>site columns" but i can not find the Title column. so i went to "site collection>>site settings>>site content types" from there i can access the Title column from one of the content types which uses this site column, so i set a defualt values for it as follow:-
but i have noted that the Title is inside a group named "_Hidden",and also it is not listed inside the site columns (as mentioned above), so does this mean or gives an indication that we should not modify the Title site column ? i mean since this column is not available inside the Site Columns and it is placed under the "_Hidden" group so is Microsoft trying to say that we should not modify this site column ??
