1) Some coloring issues will be fixed in 2.0.4. However please note that CintaNotes uses only the hue of the selected color, to ensure that all tabs have colors which are evenly bright and look good together.

2) Seems to be a bug. Please post this as a bug report here on the roadmap.

> How does notes saving to db-file works?
The note is saved when you press the OK button, or Ctrl+Enter, or ESC.
You can also save manually without closing the editor via pressing Ctrl+S.
An autosave feature is planned for the future, you can vote for it here:

>What settings should be made in the "cintanotes.settings" file for the safest work of the db-file, concerning notes saving to the db-file?
To ensure that no data gets corrupted even in case of a sudden system crash or hardware fault, you can set the "sqlite.pragma.synchronous" option to "FULL" instead of "OFF" in the settings file. This, however, will introduce a noticeable delay to all saving operations.

>How to change type of a font and its size for a editing notes window?

As Thomas has said, you can change the font settings with the "Options -> Notes List..." menu option. They affect both the notes list and note editor.

>what policy of updating of the license after 1 year of free updatings? Interesting price for Russian users?

The cost of 1-year updates prolongation will be 50% of the actual license price. (Please note that the actual license price is used and not the price which was paid a year ago for the original license.) So now it will amount to 199.5 roubles.

>Will we get colored flags AND colored tags?
No

>Or will they be the same
Maybe. something like an option "display this tag as flag" or "display this tag as a checkbox"

>Will the flag have a connection to the tags
It will.

>how will I define which status corresponds to which flag
In the tag's properties

> will it be just a graphical thing without any additional functionality
At least it will support some extra control elements in the note's preview, like a checkbox
