Right Note, for instance has a strong horizontal (x axis) implementation combined with an explorer tree on the y axis with multiple levels, I think. This could be given an arbitrary tab-interface score of maybe 8.5 on a scale of 10, real solid and strong, not spectacular.
The reason this is helpful is that often your major categories, such as finances, web, spirit, software, etc could be the Y axis distinction, while the specific topics could be X axis, Within the specific topics, then, the Explorer tree would only get moderately cluttered. The whole purpose here is to keep a bit of top-down thinking so that the Explorer tree does not have to be frequently opened and closed and navigated to find the present topic.
I have only recently started using RightNote but so far it is able to do most everything I've needed or tried. Purchased it during the BDJ offer.
The X Y axis is present in RightNote, they are just opposite of your above quote. Categories (Pages in RightNote) are the X and specific topics would be the Y (Explorer window.) This better fits my usage and I guess thought process.
I also like that it allows me to choose the type "note" I prefer in each category. Each can be any or combination of Memo, RichEdit or RichView (still figuring out the differences of the two,) Source Code or Spreadsheet.
A major example -
** I would like my major colors right on the button bar, rather than a pull-down pallet and choice. **
Is this implemented here or there ? A note is much more usable if you can color-code on the fly, very simply.
Unfortunately I haven't found a single button method but it is still relatively easy to change the color through the right-click context menu. Plus through the context menu a different icon can be added to each note, child or sibling.
Another big issue is an active user forum, a rarity in the Note field. Worthy of discussion, too, as it has a lot to do with where we settle. Right Note is considered excellent despite this lack, but it should be noted. The developers should be encouraged on this, even if it is done by a Yahoogroups or Googlegroups type of forum, or even attempted by letting Donationcoder or another forum host. (Wilder's does this a lot with security software, quite successfully.)
It's also unfortunate RightNote doesn't have a forum for sharing of information... yet. I am hopeful it is only a yet
and one will be started. I saw that you posted regarding this on BDJ.
I'm not sure how their support by email is doing so far. I sent a question and haven't heard back yet. Being fair, it's only been ~18 hours since it was sent.
