Haven´t bought this plugin (yet?) but it looks really useful. Especially the grid view and scroll view.
You would just be paying somebody to do the tedious part if you buy that.
Of course, that´s the essence of most products and services. I actually have my own little plugin for buttons (and most other stuff the plugin does I have done with simple events), but the mentioned scroll & grid view... look tempting and I´m not 100% sure how I´d approach this with native construct. If paying 20 bucks saves me more than 2-3 hours of work, maybe even work that I don´t wanna do, that´s 20 bucks well spend.
