Hi @Districh-ru , I left multiple comments here. Could you please check them?

Hi @Districh-ru , I think creating separate functions to return text instead of the proposed container would be even better solution.

Hi, @ihhub, sure. Initially I was thinking about making such function.. :)
I'll address your comments a little later.

@drevoborod , could you please test these changes? You will need a debug version of the game. Press E in the Main Menu to open the Editor.

Checked the following:

• select terrain/object type;
• select Brush size;
• add right click tips for Brush size;
• add right click tips for terrain/object type;
• add text for selected terrain/object type.

@Districh-ru , no issues, but:

1. is it OK that no type of selected brush actually allows to draw anything? And same to object selection - actual objects selection window does not appear on clicking to corresponding buttons?
2. Is this text correct? Actually this unlimited size brush can be used not for cleaning but for creation of large size areas.
   
   And in formal editor2.exe there is other text:
   
   Looks like you'we taken this text from the case when eraser is selected. In formal editor2.exe these two texts differ depending on what is selected: some terrain or the eraser, and in current editor's revision there is no separate text.
3. By the way, should all these texts be same as in formal editor? Some of them differ.
4. Seems like in these messages there should be a non-breaking space between an article and a noun:

Hi @drevoborod , answering your remarks:

1. Yes, it is not implemented as a part of this pull request.
2. Good point. I think we can address it in a separate PR.
3. No. We don't want to replicate everything as it is. We want better :)
4. It's the way how text rendering works. We might change texts for these dialogs in the future.

Hi @ihhub and @drevoborod, I'll address points 2 and 4 today a little later.

Hi @drevoborod, the brush size texts are now separated to draw/erase and a/an article in object type descriptions is moved to a new line.
Could you please check these changes when you have time.

[drevoborod]

the brush size texts are now separated to draw/erase and a/an article in object type descriptions is moved to a new line.

Checked it. Now it seems OK for me. But I noticed another minor issue. It's up to you to fix it or not:

I suggest to place "4 by 4" and similar texts on the same line, so possibly it could be better to leave them on the first line.

[drevoborod]

Checked last changes - for me it looks OK now.

@Districh-ru , well done!
