I'd prefer the very small buttons beside each topic be larger.
Perhaps rectangular as that won't increase line spacing.
I do a lot of viewing and some posting on my 8" or my 10.1 Samsung Note.
Latter has a stylus so that makes a direct hit easier.
With big fingers those tiny buttons are just that, tiny.
I look at the reviews on Tapatalk, but haven't been convinced I want to go that way and can't comment if that makes it easier in that department.
Not having used it I am perfectly happy with standard format, just the small footprint for those micro buttons.
Is that something easily accomplished? There's plenty of screen space to marginally widen them.
Regards
Richard
