moving the lock button on the left of the bar could increase the usability becouse usually the bar is very long and one start to write on the left and to use the lock has to move to the end of the window on the right
Not a terrible idea.
Here's a patch: https://phabricator.kde.org/D21177
Git commit c22df71df28315b8b1964671d3452fad5b6ae0f5 by Nate Graham. Committed on 26/05/2019 at 03:32. Pushed by ngraham into branch 'master'. When filter bar is focused, switch to view when tab key is pressed Summary: Various people have requested that the tab key move keyboard focus from the filter bar's text edit field to the main view. It already does this when the Enter and return keys are pressed, but apparently this is not very intuitive and people expect Tab to work too. This patch makes that behavior possible by moving the Lock button to the left of the text edit field, and re-arranging the code so that the filter bar is initialized first. This works because Qt assigns tab ordering by default according to the order of widget construction. So if we simply construct the main view right after the filter bar, then the tab ordering is set up this way automatically. Related: bug 403379 FIXED-IN: 19.08.0 Test Plan: 1. Activate Filter bar 2. Hit Tab key 3. View has become focused 4.
