well there are a few other options;
- shortening the names of the shortcuts that have the longest names in each row (as the width of the row is determined by this)
- adjusting the screen resolution (if it isnt already maxed out), although this affects alot of other things..
- And if still needed, reducing the font size, and adjusting padding, its sorta for advanced users though
you have to download reshacker, open the .skin file your using and find the font entries and edit them, then save and move the new file back to your skins directory, then select your new skin (unless you replaced the old one)
If you cant do this, and still want it done, just tell me the theme you are using, and the font size you want...
As far as horizontal scrolling that is a good idea, since it would only affect the users that need it
, and wouldn't even need a new option (it should be obvious that the user wants to see everything in the start menu, so if it doesnt fit on screen... scrolling should be automatic)
However im not the developer.. so its not up to me to add it... (it may be deemed to much work, for to little of a crowed)
