"I tend to be wary about programs that like to bundle everything and the kitchen sink and I can see this happening with TreeDBNotes Pro. They already have a LOT going on and the interface could be more intuitive. Still, it's the best alternative to Winorganizer I've come across (and I've tried quite a few apps), so thanks for mentioning it."
It's a tough call. If you can indeed bundle "everything" and hit the slam dunk/home run, then you become the market leader or at least a top-5. I don't think I see a spreadsheet "module" but then, I tend to think of spreadsheets as something for Excel and LibreOffice to deal with, not a note app. (Though I can certainly see how an integrated table would be nice!) In a way you have two different comments going on - "distrusting bundling everything" yet you chanced on something they chose not to get into. Softwares go through "cultures" so their feature set must have been what their specific users and/or developers wanted most.
Sure, the interface has some quirks. But overall it's also important that there is a "completeness" of features. TreeDB has a few good ones that include keyboard shortcuts to move nodes around, etc. They misbehave a wee bit, but not bad.
My overall message is if you have 3 programs fighting each other for your next use, what is the 1-2 drop dead must-have features that simply shut everything else out of the picture? For me it was that web ebook creator, and some of the importing, and lesser, some of the node handling. If you get too simple with a program you risk a kind of "data lock in" that the minute you want an advanced feature you didn't think of 3 months ago, you're hosed.
