[opensuse-kde] KDE design / style

Hello, after working in one project with a photo/ picture programm for Windows from Adobe I found that program in some cases more space efficient - eg. smaller fonts, little space between checkboxes etc. I like unices and especially KDE for their efforts in beeing consistent in design (even the utilitys for burning, musik, scanning, ... :-) and therefore I dont want eg gwenview, digikam, amarok, k3b developing their own UI but... Is there a possibility in (SuSE)-KDE-design to allow sort of "small screen interface" or to implement special design rules for some parts of the UI? I hope that my question is understandable... Greetings Christian Lorch
