I’m aware that DEVONthink has a policy of not commenting on future releases. I wouldn’t expect them to.
However if in some hypothetical future DEVONthink was developing a version 4, I would love to be included in the beta testing group.
I don’t know what it is. I kind of sense that there’s something in the water, but maybe I’m wrong.
Yes, we are hard at work on the next major version.
Just hold tight.
Yeah, there was a book mentioning that the new version is coming out soon. It’s the manual one. 
They’re never going to hear the end of it!
I really really hope that version 4 will have thumbnails as in version 3. Because thumbnails are only a hidden option, it seems they are not valued, but for me they are the best feature in Devonthink because much of my data is visual. The ability to change the thumbnail size is also very useful.
I don’t know what you mean by this.
Hi Bluefrog
If I don’t have this correctly selected, then in the configuration I use, I don’t get to see the contents of groups as thumbnails. It’s highly valuable to the way I work, but not available without setting this hidden option. It might just be relic from Devonthink 2, but it’s really useful. In widescreen view, I have my databases in the left hand column, a tree with groups and files in the centre column, and the ability either to select a file in the tree so as to see it in the right hand pane at full size in that pane, or to select a group in the tree to see all the files therein as thumbnails. I can vary the size of the thumbnails, depending on how many thumbnails I want to display. For me it’s perfect functionality, but seemingling only an afterthought in Devonthink 3. Hence my anxiety about what might happen in Devonthink 4.
Yes, that hidden preference has been removed for DEVONthink 4.
It’s now a non-hidden preference 
And NO, I am not letting out any more secrets.
That’s made my weekend!! Thank you for the advance disclosure, Bluefrog. Very much appreciated.
Jim, when are we going to see DT 4? Before or after June?
You’re been on these forums for almost five years so you should know we don’t give out development timeframes.
Jim, I know it, but there’s no harm in asking 
True and it’s a definite No if you don’t ask… even if it’s still a definite No
FWIW, I would love to be included in that hypothetical beta testing group too. I’m glad to hear a new release is growing close. I think I’m actually pretty satisfied with the application as it is, but the team has been finding ways to add additional value as long as I’ve been with the product. So this should be fun!
I hope discussion of continued support for CoverFlow will not be under NDA for testers of any hypothetical updates.
What a missed opportunity to not announce DEVONthink 4 on April 1st…
Trust me, this was discussed However, not everyone has a sense of humor and given how we’re all chin-deep in work, we opted to avoid the flak.
If it were me I would have pitched this as a starting point…
New, from the people who brought you the end of NeatReceipts, Evernote and Paperless, it’s the faceless mob of Private Equity Investors here to gut your favourite software with meaningless changes and never ending quests to shift you to a monthly fee for ever-diminishing functions and evaporating stability. Their first product is available now.

Well, DEVONthink 4 is entirely voice-controlled already! It’s quite shocking, honestly. No more menus or buttons at all. You literally speak all your commands to it. And due to macOS’ dictation mechanism, you have to speak more loudly than normal but we can’t fix that for Apple. But all commands work from what we’ve tested. So it’s no longer File > New Database but “Hey, DEVONthink! NOW MAKE A NEW DATABASE NAMED PERFECTLY NORMAL IN THE DATABASES FOLDER. AND PLEASE IMPORT MY ICLOUD EMAILS FROM TODAY INTO IT!!”
(… and yes, April Fools )
Hey DEVONthink, make me smarter
