I see qlearly now
Like some others here, I have tried many tools. There were really many bookmark/linklist/startpage solutions I tried. Once upon a time, I tried to program something like that myself. Somehow I did other things then. Anyway. Above all it should be simple.
What can I say? Yes, Qlearly is almost exactly the tool I always wanted. Open a new tab and you have the links you need right in front of you. Click on it and be there.
Using folders and boards you can sort everything finely. You can create folders that contain boards. These boards can be filled with columns. Drag and drop works as well as moving or copying the columns within the boards and into other boards in other folders.
You can save all currently opened tabs via the button "save" in each column. Of course you can also open all at once.
For me not so important but also well done are small notes and tasks, which you can also place between the links (helpful).
Admittedly, I also had some problems with the synchronization at first and was quite frustrated. After the friendly developer had switched me to the new server everything runs smoothly in/between Brave and Chrome.
I am unfortunately not a chrome fan and would be very happy if there is again a proper version for Firefox.
