I should've added this to the last message, but this is my tab bar configuration (just a little bit over engineered): (init-base-customize display-time-format "%H:%M %d/%m/%y" display-time-mail-function #'ignore) (display-time-mode) (setq global-mode-string '(:eval `("" ,(and (boundp 'init-gnus-unread-mail-string) init-gnus-unread-mail-string) ,(and (boundp 'init-gnus-unread-news-string) init-gnus-unread-news-string) ,(and (boundp 'init-volume-string) init-volume-string) ,(and (boundp 'emms-mode-line-string) emms-mode-line-string) ,(and (boundp 'emms-playing-time-string) emms-playing-time-string) " | " ,(string-trim-right display-time-string)))) (init-base-customize tab-bar-format '( tab-bar-format-tabs tab-bar-format-align-right tab-bar-format-global)) (tab-bar-mode) ('init-base-customize' is just a convenience macro which calls 'customize-set-variable' under the hood and the value of 'init-*-string' is a string of the form "x: y " where 'x' is a letter and 'y' is a number or percentage; 'x:' is replaced with an XBM image using the 'display' property on GUI frames). > Could you then try something like this to see what number it > returns? I did some further testing, first adding arbitrary text to the 'global-mode-string', then adding more images and finally adding both. I've attached screen shots of my full Emacs frame with an example of each test case, taken right after evaluating your provided expression (so the number is shown in the echo area). The buffer shown in the images shows the exact changes I made to the 'global-mode-string' in each test. I've also attached the envelope and volume icons seen in the screen shots, just in case they may be useful. Hopefully this information proves useful, thank you for looking into this.
