One of my customers of my full-time job needed a specific module that would allow him to track the number of submissions for an important petition he started in Switzerland. His site is using the excellent ChronoForms tool, but a quick glance at Google didn't show up anything specific to the task, so I decided to help him out by writing a custom module that counts the records submitted so far, along with a target value they are trying to reach. I went a little bit further than that and enabled, along with the "simple" counter view, also a Progess Bar view that visualizes the progress made by his petition with respect to the goal they set.
PS: Work on SimpleCalendar 3.1 is going forward and I'm currently testing Joomla 3.5 compatibility in different PHP versions. Will take some more time, time that I hadn't anticipated, but I'm confident we're not far off.
