Newsletter templates page takes long to load

Hello guys! I already reported the issue and suggested an improved via e-mail, but I wanted to do it here as well. Maybe there is an update on this.

The issue is:
Whenever a new e-mail is created and then “Newsletter” is chosen from the options, the templates are loading. So far fine, but in my system there are over 100 templates (customized and saved). This page now takes really long to load. There is no pagination and I can see that the full body if the templates is loaded at the same time on this page (so that you can immediately preview the template by clicking on “preview”).

Any chances we optimize the speed here and/or put pagination on this page? Thanks!
