I did check after reading this comment out of interest. I think you should experiment a bit.
So much in DEVONthink 3 ‘depends’. It depends on one’s exact use and needs but it has to be said, like with everything, some adaption is quite acceptable. In list view on my main database I have only three columns, I also have a MacBook Air and quite small screen. I have a workspace set to that that I can trigger from shortcuts. Then I use command + 5,6,7 to toggle the views, it is very quick and easy once you have a bit of practice.
Do you use workspaces they are very useful and snap into what can be otherwise quite a time consuming ‘set up’?
I don’t really have trouble seeing what I have there anyway but as an experiment I found that I can see a title of over 21 words. I could see every word of a document title which was the full citation including page numbers of an article I was using. This one, just to show you how long a title can be in the method I describe and fully legible. Myself I don’t need more than “Marios Koustakos et al. 2021. Inlfuenza lineage… 12. 741-742” as it would show in a more compressed form.
Marios Koutsakos et al. 2021. Influenza lineage extinction during the covid-19 pandemic. Nature Reviews Microbiology. 19(12). 12. 741-742
There was no truncation and I still had two columns and I could have still read it fully with another column I sometimes use.
