As you can see I have all the locales enabled, and when i start to add a table , i cant see column names, and there is no option that resize ALL the clumns to their names so i can easily see the right locale column when scrolling.
There should also be another option to search columns.
You can right click the header and choose resize, although this will resize to fir the current window which probably wont help much as you have so many languages. You can also right click and turn off the languages you dont currently need to reduce amount of columns.
There is a search bar at the top of the window that does this.
There is no turn off all option. Its a good idea, ill make a note to add one.
The search bar only turns the rows on/off, it doesn’t change the columns.
