Here are few FAQs worth noting
Why are some activities permission denied? and is it possible to give permission?
Android allows marking activities as private to prevent them from being launched by other apps. If an activity in an app is marked as private (by disabling exporting outside), system will denies to launch it. It is not possible to launch these activities as regular user.
How to remove shortcut watermark (arrow icon)?
Regular shortcuts are created by system and launcher with the provided icon and label, that is why it contains watermark (some launchers allow hiding this watermark in their settings). You can create shortcuts without watermark through shortcut widgets. Drag and drop shortcut widget of Quikshort and select/create the shortcut. You can adjust widget and label spacing in app settings.
Why are shortcut widgets looking different to regular shortcuts?
Regular shortcuts are created by system and launcher with the provided icon and label, that is why it contains watermark. In latest Android versions, the regular widget way of creating shortcuts is deprecated. For this reason, I have implemented a way to create shortcuts through 1x1 widgets. This 1x1 size varies from device to device and launcher to launcher. That's why you have options to configure this shortcut widget spacing in app settings.
Why only one browser is showing in website shortcuts?
In latest Android versions, system only provides details of default browser. That is why the app don't know that other browsers exist to launch that particular shortcut. I am planning to explicitly provide list of popular browsers to select. Feel free to contact for any browser addition to the list. Meanwhile, you can create shortcut to different browser by following this guide.
