Toolbox zoom and hand tool on same tab instead of separate tabs making it slower to select since having to flip back and forth all the time
Previous versions CS6 etc had the toolbox panel better laid out: Hand tool and zoom tools were on a separate tab now CC doesn't give the choice but having them both on a same tab so having to hover, drag etc every time I want to select my favourite tools is really tedious whilst there are many useless tools on the toolbox displayed why changing a feature that worked perfectly in previous versions?
The original toolbar with all the tools in classic arrangement is still available as 'Advanced' and can be enabled from Window > Toolbar menu. The currently offered toolbar is called 'Basic' and serves the purpose of making new users fell less overwhelmed with the amount of tools Ai has and display the most popular only.
A questionable decision, but it came with the possibility to make our own customized vertical tool panels. Read more about this here: https://helpx.adobe.com/illustrator/using/tools.html
If you want to have horizontal toolbars (as a separate option, along with 'torn-out' groups), vote here: https://illustrator.uservoice.com/forums/333657-illustrator-desktop-feature-requests/suggestions/38230498-the-illustrator-toolbox-should-be-able-to-display
If you want to be able to add dividers in toolbars (we lost them when customization had been added), vote here: https://illustrator.uservoice.com/forums/333657-illustrator-desktop-feature-requests/suggestions/38097085-add-dividers-to-custom-tools-panel-or-enable-stac#comments
Tx for one option Kevin, but it still doesn't fix the problem if you've set up a custom toolbar. Mine's organized under a custom workspace that works great for the work I'm normally doing, and I don't need all the tools showing in the advanced toolbar all the time. So I do hope we are not restricted to keeping certain tools in certain fly-out menus, since frequency of use is sometimes a more useful arrangement on the user end. (But still, I might just go back to the advanced toolbar in the meantime...or try to remember the z & h keyboard shortcuts!)
Change "All Tools" to advanced under "edit toolbar" , and it separates them :)
