Hi @Beruck
Welcome back to the community. For one thing you could use CSS to hide these (I’m sure it might be possible to use an app but it’s a longer way that I’ve not tested).
You could use the code below:
.main > div:nth-child(n+4):nth-child(-n+6) {
visibility: hidden;
}
The screenshot’s code change the background to red to illustrate that the code should only affect these elements. Note that if any updates happen to the header bar (whether the updates come from the core or another external app) this code will have to change too i.e. it only works for the current header bar where the elements are numbered and ordered exactly the way they are.
Maybe this could help:
Hope it works, looking forward to hearing back on how it goes. Thanks!
