Shade, my biz group is recently working with one online, Kanbanchi. I think they are good for visual collaboration, my sense so far is that they are not as excellent for a full blown note replacement. Remember, I am using Notezilla as, more or less, a replacement for most of the things for which I would normally use Rightnote, Keynote, Treeprojects, etc. It is true that the Kanban joins Notezilla in addressing one of their lacks (non-column orientation) so in that sense it should be looked at. Plus, any time Rightnote, etc. have a solid column orientation, I would look at it again. Anyway, Shade, I will look at Kanbanchi and any others with that idea in mind, could they really become a full-blown note system? (Possibly by using urls to your shared Google Docs, possibly if they have decent native editing.) They would have to have the tree indexing, the fine RTF, take pictures in natively, good search, etc. The colorful aspect and quick use of Notezilla is one reason it is so pleasant to use. Plus, the stick to windows would generally be missing in a Kanban, and that is key to how I use Notezilla. Hmmm...
Gautam, I will write you this AM, I was travelling for about a month in Tucson/OroValley and Asheville areas, (now back in Dutchess County, NY) so this type of stuff was low on the priority thing for a bit. Yes, the Firefox (especially) add-on, Chrome #2, would be very nice, all browsers helpful, it would shore up one area, window and page definition, taking it from very good to great. It is hard to overestimate how helpful it is to have a page come up when you open a program or web page. Your notes about something then have placement, yet they can still be found in the hierarchal tree or simply by search (which could be improved a smidgen). This 3-layer cake of finding and using notes is what really makes Notezilla, on top of the color-comfort-RTF-friendliness.
Here is another question. Any combination of "snap to grid" that lines up in columns? And/or preformats that are already lined up (e.g. in 3 columns) would be good. Granted, I can see that because of the screen variableness, this may be more work than help. Notice that this is, more-or-less, a Kanban feature brought over to Notezilla!
There is one additional area that Kanban is interesting, what you might call the "note, or document, behind the note". Would this be a feature in Notezilla? Inquiring minds... Similarly, any sort of mini-table feature might be interesting (think Rightnote) however that is getting into a whole nother realm, maybe tearing the envelope. The idea of a note behind the note, however, should be considered. True, the minimizing of a note is the current way of saving space, I may have more thoughts on this after more Kanban usage.
I think the biggest problem with Notezilla is getting people to realize its potential. Normally sticky note concepts are simply a minor aid, and I am talking about a full stretch of the envelope. However, it works!
