Without any project and/or screenshots provided it is really hard to understand what you want to change.
1) I cannot figure out where to localize the PasteHtml window title.
- would you like to change the styles of the title, or you like to change the Dialog title. In the first case, you should change the RadWindow styles. In the second case, you should change Telerik.Web.UI\Resources\RadEditor.Tools.resx
files in the installation folder. There you should find the following piece of code:
2) I've successfully replaced the image- and file managers with my own versions. Yet I cannot find the PasteHtml dialog in the dialogs folder. I would prefer to edit it somewhat, and then I guess question 1 will be moot.
>Paste As Html</
- it is placed in - Telerik.Web.UI\Editor\DialogControls
in the installation folder, there you'll find twodialogs with mozilla prefix in the name:
MozillaPasteHtmlDialog.ascx and MozillaPasteTextDialog.ascx.
The settings zones are reToolZone and reModule. Actually I do not understand which height exactly should be changed - again - without any code or screenshot showing what should be changed, it is hard to be specific.
Note also, that these custom changes are out of the scope of our support, and even if we try to give some help and guidelines it is a developer's responsibility to maintain them and to ensure that the controls will work properly.
