		elexisUnsubmitted Not Done Inline Actions Before someone suggests removing the comment, one could also check whether it would be more logically consistent to not introduce the inheritance, or to inherit but use it for both text renderings, since there would be 3 lines using the new IGUITextOwner inheritance vs. 2000 lines managing and rendering text without IGUITextOwner. The class should use the IGUITextOwner if CInput shall be able to print selectable colorized, perhaps link-clickable text, for example for ToS, chat, mapdescription, but would require rewriting the entire class (and D1781). elexis: Before someone suggests removing the comment, one could also check whether it would be more…
		SilierAuthorUnsubmitted Done Inline Actions IGUITextOwner is used to prebuild string, but caption of input will change too frequently to benefit from that.

		elexisUnsubmitted Not Done Inline Actions Perhaps `CGUIText` could be used to support tags (such as font) and avoid `m_PlaceholderColor` (or perhaps CGUIString is more consistent with COList columns or something, dunno, but there are those two possibilities. Actually COList seems to use CStrW, so there are three. CStrW would be consistent with m_Caption.) elexis: Perhaps `CGUIText` could be used to support tags (such as font) and avoid `m_PlaceholderColor`…
