These directions are all from my experience with Chrome, but will probably behave similarly in any internet browser.
I just wanted to point out this quick tip that I use often on Pinterest, but can be used in lots of other situations. Whenever I pin a layout on Pinterest I always describe the pin using photo number and basic techniques and elements used, ex. "1 photo + paint + wood + brads." Then later when I'm looking for a layout with paint, I open my layout board and type "ctrl+f" (cmd+f on mac). This will open a little dialogue box at the top the screen (1). In the dialogue box you can type what you're looking for. The box will then show you how many of that word appear on the page. By hitting enter while still in the find box, you can skip between the words on the page, which will appear highlighted (2). You can also get a clue where they are by looking in the scroll bar on the right (3). Basically this is a way to hack tagging on Pinterest, allowing you to find things more easily.
