Here's my attempt at recreating the template with a timeline template. I've tried to keep it as simple as possible, and used a bit of artistic license in the process. It's not necessary to list every single name change on the template, that info is better left on the relevant pages themselves. Any critical information I've left out or improvements to be made? - Hivebrain (talk) 12:12, 14 April 2017 (CDT)

I did not know that you build a template like that more simple, Black Squirrels template I could not figure out.--Trippled (talk) 16:46, 14 April 2017 (CDT)

Be very careful not to have overlapping dates. It doesn't take that into account when calculating colspan. - Hivebrain (talk) 17:20, 14 April 2017 (CDT)
