For each entry some information is displayed along with a delete and a download button. They are only visible however if the operation is permitted for the particular element (e.g. no deletion of demo charts or system layouts).
Eventually more icons indicate operations valid for this element. By clicking the element a dialog will open displaying available actions for the element.

If available ("Edit" / "View") you can switch to an edit/show view. For routes "Edit" will bring up the Route-Editor.

In this view you can make changes - (caption "Editing" ) or the content is dispayed. By clicking the changes will be stored.

Special Functions

User Files

Switching to user files permits to e.g. edit user.js and user.css. The file keys.json contains user defined keyboard shortcuts.

The file images.json can be used to adapt some of the symbols in AvNav.

Here you can also upload additional files needed to adapt AvNav (e.g. css files, java script files or HTML files). These files can be accessed via the url /user/viewer/<name>.
Images should be uploaded in the Images category. They will be accessible via /user/images/<name>.

Clicking the "+" button (lower right) you can create a new file. This could be a HTML file to create a User App .

For a HTML file the action dialog contains an "App" button that you can click to directly create a User App. You have to be sure to upload an Icon image file beforehand.

Charts - mbtiles Format

Using a mbtiles chart could lead to problems if the tiles internally are not ordered according to the default "xyz" format. Unless valid information is provided in meta data, AvNav assumes "xyz". If you experience display problems with a mbtiles chart you can try to set the format to "tms" within the action dialog. This change will be written to the chart file.

Chart Upload

At the category you can directly upload chart files. Files that can be handled by AvNav will be uploaded directly into the charts directory and will be available immediately (gemf, mbtiles, xml files).

For charts requiring Conversion you will be asked if they should be put into the importer's input directory (not on android).

You can optionally select a "set" name - this determines name of the gemf file to be created. This way you can merge multiple chart files into a single gemf file. The state of conversion can be checked at the import page (it will be opened automatically).
After an upload the importer still waits some time allowing more files to be uploaded and included in the same set. They all will be handled with one conversion.

Tracks

The info dialog for tracks contains some additional information.

Additionally the conversion of the track to a route can be started with the  Convert button. Clicking the overlay button you can add the track to overlays or remove it from them.
