csIcaK · web-flow · commit c27bc6449c0d · 2023-12-06T07:48:57.000+01:00
### Changed
- added text to display while loading the content.

### Reason
Currently on bigger projects it takes considerable amount of time to
load the location of the selected ID. During that time currently there
is a blank page shown to the user.

This change will display a static text: `Searching, Please Wait...`
