Just tested The Guide and it crashed within two minutes use. It has a severe bug and crashes on startup if you have selected "Load last used document" in the preferences. As development seems stopped it is unlikely the bug will be fixed.

Lots of potential. I currently use whizfolders and like the cleaner interface of the Guide but one feature I consider critical is the ability to copy nodes between documents.

I tryed to install The Guide on Ubuntu via Wine, but it doesn't work.
Exist similar product on linut (Ubuntu)?

Where is password protection?!!!!! Not useful without it.

I also totally disagree with the comment about TotalText being a more mature product. I previously tried it and it was buggier than a pond of mosquito larvae. People were complaining in the comments for TotalText, I found there was a bug fix for some of the instability problems so I downloaded the latest version and gave it a try. Based on that, I gave positive feedback, it seemed ok. A day or two later I went back to look some more, and it was misbehaving again, even after a reboot and no other apps running. Back to the mosquito pond ... I deleted it and won't bother again.

In contrast, Both The Guide and Mempad are truly stable, both good in their own ways, but I think The Guide has more potential if the developer takes note of my (and I assume) other suggestions for password protection and encryption, multi-window / multi opened file support, and others.

Totaltext seems to have more features, but considering I got one unexpected exit and one c++ floating point exception within a few minutes of trying it out, I disagree with the description of Totaltext as a "more mature product".

Ack. These are less than steller. Guys, try out Totaltext, a much more mature product. Even the old Keynote from 2000 beats these poor examples of outliners.

I should have added above, one thing that really makes search far better in The Guide, is that if I type Ctrl F and then a word. e.g. 'split' Mempad searches and shows each occurrence of the word split. The Guide shows me a dialog box with a fragment of text containing all occurrences of the word split so that I can far more quickly choose the one I want and go right to it, instead of F3 / Shift F3, or arrow clicking backwards and forwards looking at every occurrence to see if it is what I want.

Better is very subjective.

Mempad uses less memory, it does have password protection and encryption, but it does not have the ability to to have Rich Text formatting, export to RTF, embedded graphics capabilities, different fonts and colors on the same page as well as highlighting again, different colors on the same page), icons for different nodes in a tree, check boxes, bullets, numbering, search doesn't work as well for me as The Guide.

I like Mempad, but I think The Guide has far more for me than Mempad. I have already suggested password protection / encryption and a few other new features to the developer of The Guide. It could well be better (more features) than Mempad if he's as receptive to adding features as he says on his web pages / forums and just adds a few new things.
