Currently the L (lowercase) and I (uppercase) look the same in MP3Tag, can you please change the font for one that shows "more" different chars for those two letters?
SubtitleEdit had this problem and they fixed it using Tahoma as the font, I don't know of any other font that shows different chars.
Oh, yes, but the other applications, at least the ones I use and that rely a lot on text, have the option to choose the font to use within the app. XRecode, XYplorer, SubtitleEdit, MKVToolNix and foobar2k to name some. Would be great if we could choose the font in MP3Tag too.
