P.S. My English is not excellent, sorry for that. Attached images can explain my suggestion better. In a nutshell, between the attached images, I’d prefer to use (C) or (D), rather than use (A) or (B).
At the Image-1, buttons in the menu which I marked with (A) are too small and useless. Also there are some mismatches between (A) and (B) menus.
1. Square shaped buttons located in menu (A), are 2 px smaller than the buttons in menu (B).
2. The view of the icons is different. Icons located in menu (A) have border around them. But icons in menu (B) don’t have border around them. Icons have a clearer view without border.
3. Placement the icons is different, too.
4. There are different border options. For example, there are diagonal borders in menu (B), but there aren't in menu (A).
Because of all these reasons, I suggest to readjust the menus with same form at Image-2 for being compatible with one another and presenting a useful content. Option (D) of Image-2 is connected with the result of ID: 100548 bug record. If number 100548 bug record is accepted, all border options can be done compatible with eachother by using option (D).

OK, also seems reasonable. But same question as in bug 100548 about "loss" of the existing preset border selections while making them larger.
I think it would be reasonable moving it this direction, but not sure if we could even use the multi-line picker of mockup (D) in the toolbar .UI GTK button box -- Samuel, Tomaž?
Otherwise we should attempt to make the layout of the Cell border settings on each of the--Toolbar, the Format Cell dialog, the Sidebar Properties deck Cell Appearance panel--consistent.
From the HIG : "Prefer controls where the setting is one click away...", "Consider introducing presets of properties comprising of the most relevant settings."
So I would make it even simpler with no floating widget containing all border settings but the most relevant three (none, outline, grid). And of course easy access to the dialog.

Ya da Image-3'deki gibi olabilir. Bu menünün bir şekilde iyileştirilmesi lazım.
(Excuse me, I forgot English translations)
Or it may be as Image-3 wherein. This menu is somehow need to be improved.

Well the other way to go would be to make it a split button and stateful to remember the last applied style on button click or drop the picker.
As in bug 58349 - Turn Border button into a split button.
