first of all I need to congrats you for this extremely useful plugin.
Second, is there any thought in removing the Read More Button and making the picture of each item clickable?
If it is not considered, I would be grateful, if you could inform of the changes needed to be done for this, if it is possible, since I think that many users of this plugin will find it extremely helpful.
I had previously mentioned a custom.css file which can be located in the active theme folder. This would also allow for the input of a custom icon or button by using css to do the work without intrusive code in the main plugin file. It only takes a few lines of code to add in, and this technique has been used in NextGen Gallery as well.
