Let's see. Most forums (the ones that are supported - Thanks!) that I use in one place. Threads that I subscribe to in one list, threads that I've posted in in another, Unread threads in still another, and most recent threads in still another list - all with unread threads highlighted. I don't have to remember the 12 different ways 12 different forums contain links to those lists. No ads in Tapatalk Pro that I bought MANY years ago and have not had to pay again since. It runs pretty much the same on all three of my Android devices (although I seldom use it on my phone). Pictures easily downloaded. Pdf files easily downloaded. Web links work fine. I seem to be able to go back and edit just fine, within the limits set by the individual forums (some seem to set a time limit). Oh yes - and I can use it on my tablet! I keep an old one in the garage so I can reference right there the great things that you guys post!
Drawbacks: no spell checker! That is automatic on my browsers for computers. Posting pictures is hit-and-miss. Mainly an Android and device memory issue, I think. Not supported by ALL forums (NGW doesn't). And, you have to use a tablet keyboard, which I mis-type on constantly.
BTW, I just added this by going back and editing my post. Tap on your pist, te upper left gets a tool added, tap it and select Edit.
