How 1P Displays

I am really getting perplexed.  I posted yesterday asking for help and that post does not seem to be anywhere.  Somehow I changed the way my 1P shows when I open it and I can't figure out how to get it back to the format I prefer - which shows my sub-categories or tags on the left side - like Airlines, credit cards, banks, veteran sites, etc.  And further perplexing is I can't seem to upload a screenshot so it helps my explanation because everytime I try 1P says the file is too big.  I am really at a loss.

Thank you
