I downloaded the latest CintaNotes installer, and ran it on my Lubuntu OS through Wine Windows Program Loader. The installation proceeded perfectly. It even created start menu group and a shortcut on the Desktop, and its icon came in the taskbar.
All of this on a Linux OS!
Then I opened it. These are the things that work:
1. Import XML : imported all my notes that I'd exported from Cintanotes in my Windows machine.
2. Main application, tags pane. Clicking on a tag, showing its notes
3. Search, all kinds of search. Search-as-you-type. Tags show up as you type them.
4. Order notes by by modified/created/etc
5. Deleting a note : popup asks if we want to move to Recycle Bin.. popup opens nicely
6. Recycle Bin : all functions incl Restore, with the due popups.
7. Right-click on a note and copy content gets copied to clipboard; I can paste it anywhere.
8. Right-click > Delete
9. Right-click > Properties : loads the properties popup, I can edit the date-time stamps and save the change.
9. Right-click > Tag : add tags, remove tags to and from notes.
10. Export as XML or TXT. (file save dialog box, browsing, saving all worked well)
11. Clicking on the note, press Left or Right keys to scroll the excerpt up or down.
There are only 3 things that are not working on CintaNotes loaded on Wine/Linux.
1. Create a new Note
2. Edit a note
3. Paste
So basically, everything except the main thing is working! When you try to create a new note or open a note, this is the error popup we get:

So please, guys, let's crack this cookie! CintaNotes is ALMOST working on Linux (over Wine)!
