How to apply html changes inside lms/templates on local environment?

Hi,

I want to change the .html files and see the changes immediately or at least without having to run launch and rebuild everything. I have managed to solve this on dev environment but I cannot find a way to do this on local environment. To illustrate this problem, try to edit lms/templates/courseware/courses.html line 32
from
<%block name="pagetitle">${_("Courses")}</%block>
to
<%block name="pagetitle">TEST CHANGES</%block>

just to test changes, on local environment, and no matter what I do, the changes will not get applied and I will not see my “TEST CHANGES” string in the head title.

What can I do?
