Font and font size in signature block

Even in this block that I'm typing this message in I can change the font and the font size but in the Hubspot sales signature entry you can't enter font or size, it requires you to edit the HTML.  How archaic is that!!!  This is obviously ridiculous especially now the Hubspot has FINALLY added the ability to change your email default font!  FINALLY!  


This kind of missing simple functionality makes me think that there is little quality management going on at Hubspot!  Yes I'm critical because this is such a simple option to add but instead the folks at Hubspot believe that editing HTML is a viable option.  What a pity!
