Hello,
My idea is:
In Mautic 6.x you can hide a theme so its not displayed in the list when you create a segment email.
However all the standard distributed themes still exist in the themes directory. If you delete the standard themes I think they reloaded when you upgrade Mautic.
For anyone that has a quite a few custom themes it would be a great idea to restructure the themes directory to separate standard themes and custom themes into separate directories:
themes
-----standard
-----custom
Or possibly:
themes-standard
themes-custom
And when you create a new segment email you could be offered either the standard set or the custom set dependant on a check box which you could tick or untick. It would also be great if Mautic remembered the check box state as well for repetitive tasks.
Thanks.
