Many thanks for this!!!
• When setting a larger View Text Size via the General > Appearance preferences, the thumbnail icon scales better, the vertical alignment of some List view columns is more consistent, and better line spacing improves readability. This also applies to the Search and See Also & Classify inspectors.
• In Column and List views an adjusted line spacing improves the readability.
You’re welcome.
I can only second that - a possibly minor yet (at least for me) very welcome improvement! thank you very much!
DT’s developers rightly say that features are more important than “appearance”. However, it is more fun to use these features if the appearance is also pleasant. And there is a stage where appearance becomes a feature. 
Another thank-you from me. I do love a bit of white space.
Sorry, I am aware that my suggestion comes at the completely wrong time, as this has just been improved in DT v 3.9.7. Nevertheless, perhaps this can be considered for a later version.
My somewhat older eyes (and they are not getting any younger 
) would very much welcome it if the line spacing between the documents could be freely selected. I would like to illustrate this using the example of another app that I think does this perfectly.
Line spacing 1
Line spacing 5
The line spacing can be as large or small as suits my eyes.
Simply copying ohters makes no sense. But it makes sense to look at the good ideas of others, because you can’t have every good idea yourself
