No doubt its very useful having tabbed pages in the PDF editor, but the dynamic size of the tabs themselves is a detriment when you have many tabs open at once. It would be better if the tab size was fixed so you can click X on the first tab and the subsequent tab taking its place has its X to close tab button in the same exact location. This allows for rapid closing of batches of tabs without needing to move the mouse cursor by a few pixels to relocate to the X's new position. It is also more conducive to macro recording / script writing when the tab size is fixed allowing the close button to be easily indexed using the rest of the UI. I am well aware that ctrl + F4 closes the tabs in a convenient way for both scripting and macro recording but not all users and or workflows can or will incorporate keyboard shortcuts over pointer input. (Not to mention using ctrl + F4 closes the current tab, then switches focus to the last tab, when it should switch focus to the next tab in my humble opinion)
TLDR: I like to post up my mouse pointer on the tabs close button and spam it to close multiple tabs in quick succession, but I can't when the tab size is always changing.
