Can I change the font, size, color or behavior of the QAP popup menu items?

Yes and no. QAP is building its menus using standard Windows commands. Depending on your Windows version, you may be able to change menu fonts, size or color in Windows Settings (aka Windows Control Panel). But you can’t change the menu font only in QAP menus.

If you want to reduce the space occupied by your menu, you can change the size of menu icons, or even completely remove them. This will allow you to have more menu entries in the same space. Open the Menu Appearance tab of the Options window change the Menu icon size. Also, you can use sub-menus to group menu entries under a single entry.

The left menu has icons size of 48 pixels, the middle one has the default size 32 pixels and the right one has the smallest 16 pixels width.

For the same reason (because QAP is relying on standard Windows menus), QAP cannot do the followings:

• Make some menu items bold: only one “default” item Customize in the Main menu is displayed bold.
• Decide on what side will popup a sub menu: this is determined by Windows depending on the space available on the right side of the menu (if not, the submenu will on on the left – I know, I hate this too…).
• Have a Live Folder submenu entry to be clickable to open the Live folder itself. In Windows menus, submenu entries are not clickable.
• Trigger an action if you right-click on a menu item: the right-click on a menu cannot be catched to trigger an action. It just does nothing (but you could be interested by these options: Can I launch Alternative menu features directly from the regular popup menu?)
• Scroll inside the popup menu using the mouse wheel.
• Etc…

The alternative would be to completely rewrite the QAP menu (using the AHK platform and much advanced libraries) but this would be way too much work and would open the door to a whole new set of bugs and issues. Sorry but this is not on the QAP roadmap.
