Thanks for suggestions! I added this to the init file, an it seems to work

;; Native buffer tabs setup
(global-tab-line-mode 1)

(setq tab-line-tabs-function 'tab-line-tabs-buffer-groups)
(setq tab-line-close-tab-function 'kill-buffer)

(set-face-attribute 'tab-line nil :height 1.0)

Is that what you had in mind?

Thanks..
