Because of "SNG" (Surfulater Next Generation), I am inclined to think the present version (without SNG) is a better choice for some. One some being me! I have a visual memory, I know where my stuff is placed because I can visualize the location. What can confuse me, is what words I should type, if I were to search for my stuff, only by using tags. Next Gen is all about tags; skipping the folders and replacing them with tags. Surfulater Next Gen is most likely not for me.
Of course Surfulater Next Gen must be expected to be version 4, a major version's upgrade.
