DevDmBootstrap3 will always be free but it does cost me. It costs me in sweat and time equity. I’ve tried to make sure I answer all of your questions as quickly and efficiently as I am able. I am also making sure to keep things updated as Bootstrap changes and constantly looking for ways to make the theme better for all.
So far we are doing pretty good. I’m quite happy with how things are going but there is plenty of places to improve and I have a lot of “ideas” on how we can make Bootstrap Theme Integration easier for developers while allowing them the control and freedom not afforded by bigger bloated theme projects.
There are plenty of ways you can support me and the DevDmBootstrap3 project.
