Text fields Into Item/Trigger configuration page could contain a lot of data, and, it really uncomfortable to debug some mistakes/ modify something  into Item/Trigger Name, Item Key, Trigger Operational Data, Trigger Event Name.

Also, current font is also uncomfortable, because  these fields, first of all,  have containing technical information, especially item key, because this field could containt really long text commands in case of system.run[*] usage

Please, make the mentioned text fields dynamically expandable, like trigger expression field

Also, change current font to monospaced font into item key field, as it is into calculated items formula and trigger expression now
