Currently (in 0.21), there are several font-size options (at least on one
screen; there may be others elsewhere):
- "Small" font
- "Medium" font
- "Large" font
- Fine tune font size (%)
If you're only talking about the last of those options, then I don't see any
point in keeping it. The others, I think, should definitely be retained, for
the reasons I specified. Your comments below make me think you may have
eliminated these in 0.22 or 0.23, but I'm not sure of that.

To what version are you referring, and are you referring to the OSD only or to
fonts in menus when not playing recordings? I'm using 0.21, and there are
definitely default, small, and big font options for the menu fonts, as noted
above. If those settings have been removed in 0.22, then I view it as a
backward step. A big home-theater setup using 1080i resolution is likely to
work better with smaller fonts than a little 9-inch analog set in a kitchen
running 640x480 via composite cables. Different themes can, of course, be
customized for different screen sizes, but that'll just force unpleasant
choices on users regarding what themes to use.
I do understand the point you're making, and I have two comments/suggestions,
one of which will admittedly be a pain to implement:
- Themes might set suggested/default font sizes, but users could still
override these defaults as they see fit. This should at least help
take the heat off theme designers.
- The sizes of on-screen elements could be adjusted depending on the font
size (or the space consumed by the formatted text to be displayed). Then
if somebody selects a tiny font, the OSD information display could be
made smaller; and if a huge font is selected, it could be made bigger.
This would eliminate your doesn't fit/wasted space objection. I don't
know how much effort this would take to implement, though -- perhaps
enough that it's not a practical possibility.

I acknowledge that this is a problem. I just think that removing font-size
options from the user interface ends up trading one set of problems (for
developers) for another set of problems (for users). OTOH, since I'm using
0.21, which still has the font options, and since I've got my system set up
the way I like it, I may be overestimating the seriousness of the issues
created for users.

Using sed (or any other editor) to alter a theme is hardly user friendly! This
is exactly the sort of complicated technical mumbo-jumbo that user interface
settings are supposed to eliminate. Even somebody who's familiar with sed
would need instructions to know what to change in the theme file -- certainly
I wouldn't know what to change, and as I'm not a theme author, I'd need to
spend quite a while to track it down. A settings option like what we've got
now, OTOH, is easy enough for anybody to tweak.
